dm integrity: fix error code in dm_integrity_ctr()
The "r" variable shadows an earlier "r" that has function scope. It
means that we accidentally return success instead of an error code.
Smatch has a warning for this:
drivers/md/dm-integrity.c:4503 dm_integrity_ctr()
warn: missing error code 'r'
Fixes: 7eada909bfd7 ("dm: add integrity target")
