The AGFL repair code uses a series of bitmaps to figure out where there are OWN_AG blocks that are not claimed by the free space and rmap btrees. These blocks become the new AGFL, and any overflow is reaped. The bitmaps current track xfs_fsblock_t even though we already know the AG number. In the last patch, we introduced a new bitmap "type" for tracking xfs_agblock_t extents. Port the reaping code and the AGFL repair to use this new type, which makes it very obvious what we're tracking. This also eliminates a bunch of unnecessary agblock <-> fsblock conversions.
