RDMA/rxe: Fix rxe_modify_srq
This patch corrects an error in rxe_modify_srq where if the
caller changes the srq size the actual new value is not returned
to the caller since it may be larger than what is requested.
Additionally it open codes the subroutine rcv_wqe_size() which
adds very little value, and makes some whitespace changes.

RDMA/rxe: Convert tasklet args to queue pairs
Originally is was thought that the tasklet machinery in rxe_task.c would
be used in other applications but that has not happened for years. This
patch replaces the 'void *arg' by struct 'rxe_qp *qp' in the parameters to
the tasklet calls. This change will have no affect on performance but may
make the code a little clearer.

RDMA/rxe: Add error messages
This patch adds error and debug messages so that every interaction
with rdma-core through a verbs API call or a completion error return
will generate at least one error message backed up by debug messages
with more detail.
With dynamic debugging one can follow up after seeing an error message
by turning on the appropriate debug messages.

RDMA/rxe: Replace rxe_map and rxe_phys_buf by xarray
Replace struct rxe-phys_buf and struct rxe_map by struct xarray
in rxe_verbs.h. This allows using rcu locking on reads for
the memory maps stored in each mr.
This is based off of a sketch of a patch from Jason Gunthorpe in the
link below. Some changes were needed to make this work. It applies
cleanly to the current for-next and passes the pyverbs, perftest
and the same blktests test cases which run today.

Revert "RDMA/rxe: Create duplicate mapping tables for FMRs"
Below 2 commits will be reverted:
commit 8ff5f5d9d8cf ("RDMA/rxe: Prevent double freeing rxe_map_set()")
commit 647bf13ce944 ("RDMA/rxe: Create duplicate mapping tables for FMRs")
The community has a few bug reports which pointed this commit at last.
Some proposals are raised up in the meantime but all of them have no
follow-up operation.
The previous commit led the map_set of FMR to be not available any more if
the MR is registered again after invalidating. Although the mentioned
patch try to fix a potential race in building/accessing the same table
for fast memory regions, it broke rtrs etc ULPs. Since the latter could
be worse, revert this patch.
With previous commit, it's observed that a same MR in rnbd server will
trigger below code path:
-> rxe_mr_init_fast()
|-> alloc map_set() # map_set is uninitialized
|...-> rxe_map_mr_sg() # build the map_set
|-> rxe_mr_set_page()
|...-> rxe_reg_fast_mr() # mr->state change to VALID from FREE that means
# we can access host memory(such rxe_mr_copy)
|...-> rxe_invalidate_mr() # mr->state change to FREE from VALID
|...-> rxe_reg_fast_mr() # mr->state change to VALID from FREE,
# but map_set was not built again
|...-> rxe_mr_copy() # kernel crash due to access wild addresses
# that lookup from the map_set
The backtraces are not always identical.

RDMA/rxe: For invalidate compare according to set keys in mr
The 'rkey' input can be an lkey or rkey, and in rxe the lkey or rkey have
the same value, including the variant bits.
So, if mr->rkey is set, compare the invalidate key with it, otherwise
compare with the mr->lkey.
Since we already did a lookup on the non-varient bits to get this far, the
check's only purpose is to confirm that the wqe has the correct variant
bits.

The qp parameter in free_rd_atomic_resource() has become
unused so remove it directly.

RDMA/rxe: Remove IB_SRQ_INIT_MASK
Currently the #define IB_SRQ_INIT_MASK is used to distinguish the
rxe_create_srq verb from the rxe_modify_srq verb so that some code can be
shared between these two subroutines.
This commit splits rxe_srq_chk_attr into two subroutines: rxe_srq_chk_init
and rxe_srq_chk_attr which handle the create_srq and modify_srq verbs
separately.

RDMA/rxe: Fix ref error in rxe_av.c
The commit referenced below can take a reference to the AH which is never
dropped. This only happens in the UD request path. This patch optionally
passes that AH back to the caller so that it can hold the reference while
the AV is being accessed and then drop it. Code to do this is added to
rxe_req.c. The AV is also passed to rxe_prepare in rxe_net.c as an
optimization.
