block_dev: use blkdev_issue_zerout for hole punches This gets us support for non-discard efficient write of zeroes (e.g. NVMe) and prepares for removing the discard_zeroes_data flag. Also remove a pointless discard support check, which is done in blkdev_issue_discard already. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K.
