SUNRPC: Add an IS_ERR() check back to where it was

[ Upstream commit 4f3ed837186fc0d2722ba8d2457a594322e9c2ef ]

This IS_ERR() check was deleted during in a cleanup because, at the time,
the rpcb_call_async() function could not return an error pointer. That
changed in commit 25cf32ad5dba ("SUNRPC: Handle allocation failure in
rpc_new_task()") and now it can return an error pointer. Put the check
back.

A related revert was done in commit 13bd90141804 ("Revert "SUNRPC:
Remove unreachable error condition"").

SUNRPC: attempt to reach rpcbind with an abstract socket name

NFS is primarily name-spaced using network namespaces. However it
contacts rpcbind (and gss_proxy) using AF_UNIX sockets which are
name-spaced using the mount namespaces. This requires a container using
NFSv3 (the form that requires rpcbind) to manage both network and mount
namespaces, which can seem an unnecessary burden.

As NFS is primarily a network service it makes sense to use network
namespaces as much as possible, and to prefer to communicate with an
rpcbind running in the same network namespace. This can be done, while
preserving the benefits of AF_UNIX sockets, by using an abstract socket
address.

An abstract address has a nul at the start of sun_path, and a length
that is exactly the complete size of the sockaddr_un up to the end of
the name, NOT including any trailing nul (which is not part of the
address).
Abstract addresses are local to a network namespace - regular AF_UNIX
path names a resolved in the mount namespace ignoring the network
namespace.

This patch causes rpcb to first try an abstract address before
continuing with regular AF_UNIX and then IP addresses. This ensures
backwards compatibility.

Choosing the name needs some care as the same address will be configured
for rpcbind, and needs to be built in to libtirpc for this enhancement
to be fully successful. There is no formal standard for choosing
abstract addresses. The defacto standard appears to be to use a path
name similar to what would be used for a filesystem AF_UNIX address -
but with a leading nul.

In that case
"\0/var/run/rpcbind.sock"
seems like the best choice. However at this time /var/run is deprecated
in favour of /run, so
"\0/run/rpcbind.sock"
might be better.
Though as we are deliberately moving away from using the filesystem it
might seem more sensible to explicitly break the connection and just
have
"\0rpcbind.socket"
using the same name as the systemd unit file..

This patch chooses the second option, which seems least likely to raise
objections.

Pull NFS client updates from Trond Myklebust:
"Highlights include:

Features:

- Switch NFS to use readahead instead of the obsolete readpages.

- Readdir fixes to improve cacheability of large directories when
there are multiple readers and writers.

- Readdir performance improvements when doing a seekdir() immediately
after opening the directory (common when re-exporting NFS).

- NFS swap improvements from Neil Brown.

- Loosen up memory allocation to permit direct reclaim and write back
in cases where there is no danger of deadlocking the writeback code
or NFS swap.

- Avoid sillyrename when the NFSv4 server claims to support the
necessary features to recover the unlinked but open file after
reboot.

Bugfixes:

- Patch from Olga to add a mount option to control NFSv4.1 session
trunking discovery, and default it to being off.

- Fix a lockup in nfs_do_recoalesce().

- Two fixes for list iterator variables being used when pointing to
the list head.

- Fix a kernel memory scribble when reading from a non-socket
transport in /sys/kernel/sunrpc.

- Fix a race where reconnecting to a server could leave the TCP
socket stuck forever in the connecting state.

- Patch from Neil to fix a shutdown race which can leave the SUNRPC
transport timer primed after we free the struct xprt itself.

- Patch from Xin Xiong to fix reference count leaks in the NFSv4.2
copy offload.

- Sunrpc patch from Olga to avoid resending a task on an offlined
transport.

Cleanups:

- Patches from Dave Wysochanski to clean up the fscache code"
