dm snapshot: fix crash with transient storage and zero chunk size

The following commands will crash the kernel:

modprobe brd rd_size=1048576
dmsetup create o --table "0 `blockdev --getsize /dev/ram0` snapshot-origin /dev/ram0"
dmsetup create s --table "0 `blockdev --getsize /dev/ram0` snapshot /dev/ram0 /dev/ram1 N 0"

The reason is that when we test for zero chunk size, we jump to the label
bad_read_metadata without setting the "r" variable. The function
snapshot_ctr destroys all the structures and then exits with "r == 0". The
kernel then crashes because it falsely believes that snapshot_ctr
succeeded.

In order to fix the bug, we set the variable "r" to -EINVAL.

dm snapshot: fix a crash when an origin has no snapshots

If an origin target has no snapshots, o->split_boundary is set to 0.
This causes BUG_ON(sectors <= 0) in block/bio.c:bio_split().

Fix this by initializing chunk_size, and in turn split_boundary, to
rounddown_pow_of_two(UINT_MAX) -- the largest power of two that fits
into "unsigned" type.

Merge tag 'for-5.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper updates from Mike Snitzer:

- Improve scalability of DM's device hash by switching to rbtree

- Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and
allow filtering based on name or UUID prefix.

- Various small fixes for typos, warnings, unused function, or
needlessly exported interfaces.

- Remove needless request_queue NULL pointer checks in DM thin and
cache targets.

- Remove unnecessary loop in DM core's __split_and_process_bio().

- Remove DM core's dm_vcalloc() and just use kvcalloc or kvmalloc_array
instead (depending whether zeroing is useful).

- Fix request-based DM's double free of blk_mq_tag_set in device remove
after table load fails.

- Improve DM persistent data performance on non-x86 by fixing packed
structs to have a stated alignment. Also remove needless extra work
from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON()
that caused duplicate checksum calculation.

- Fix missing goto in DM integrity's bitmap_flush_interval error
handling.

- Add "reset_recalculate" feature flag to DM integrity.

- Improve DM integrity by leveraging discard support to avoid needless
re-writing of metadata and also use discard support to improve hash
recalculation.

- Fix race with DM raid target's reshape and MD raid4/5/6 resync that
resulted in inconsistant reshape state during table reloads.

- Update DM raid target to temove unnecessary discard limits for raid0
and raid10 now that MD has optimized discard handling for both raid
levels.
