dm integrity: fix error code in dm_integrity_ctr()

Browse source 
commit d3f2a14b8906df913cb04a706367b012db94a6e8 upstream.

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: 7eada909bf ("dm: add integrity target")
