target: remove an incorrect unmap zeroes data deduction
For block devices, the SCSI target drivers implements UNMAP as calls to
blkdev_issue_discard, which does not guarantee zeroing just because
Write Zeroes is supported.
Note that this does not affect the file backed path which uses
fallocate to punch holes.
Fixes: 2237498f0b5c ("target/iblock: Convert WRITE_SAME to blkdev_issue_zeroout")
