xfs: correct calculation for agend and blockcount

Browse source

[ Upstream commit 3c90c01e49 ]

The agend should be "start + length - 1", then, blockcount should be
"end + 1 - start".  Correct 2 calculation mistakes.

Also, rename "agend" to "range_agend" because it's not the end of the AG
per se; it's the end of the dead region within an AG's agblock space.
