xfs: simplify sector number calculation in xfs_zero_extent

Browse source

xfs_zero_extent does some really odd gymnstics to calculate the block
layer sectors numbers passed to blkdev_issue_zeroout.  This is because it
used to call sb_issue_zeroout and the calculations in that helper got
open coded here in the rather misleadingly named commit 3dc2916107
("dax: use sb_issue_zerout instead of calling dax_clear_sectors").
