Christoph Hellwig 3eba802d47 target: remove an incorrect unmap zeroes data deduction
[ Upstream commit 179d8609d8424529e95021df939ed7b0b82b37f1 ]

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: 2237498f0b ("target/iblock: Convert WRITE_SAME to blkdev_issue_zeroout")
