dm-integrity: fix a memory leak when rechecking the data
[ Upstream commit 55e565c42dce81a4e49c13262d5bc4eb4c2e588a ]
Memory for the "checksums" pointer will leak if the data is rechecked
after checksum failure (because the associated kfree won't happen due
to 'goto skip_io').
Fix this by freeing the checksums memory before recheck, and just use
the "checksum_onstack" memory for storing checksum during recheck.
Fixes: c88f5e553fe3 ("dm-integrity: recheck the integrity tag after a failure")
