[PATCH 2/2] xfs: cleanup XFS_BB_FSB_OFFSET

[PATCH 2/2] xfs: cleanup XFS_BB_FSB_OFFSET

[Amit Sahrawat]

Removing the macro, as this is no more needed in the code. 
Tried to find the reference when it was last used - but the usage 
for this seemed to have been dropped long time ago.

This looks good, but the subject should be something like:

"xfs: kill the unused XFS_BB_FSB_OFFSET macro"
