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.
