Dave Chinner c08768977b xfs: finobt AG reserves don't consider last AG can be a runt 
The last AG may be very small comapred to all other AGs, and hence
AG reservations based on the superblock AG size may actually consume
more space than the AG actually has. This results on assert failures
like:

XFS: Assertion failed: xfs_perag_resv(pag, XFS_AG_RESV_METADATA)->ar_reserved + xfs_perag_resv(pag, XFS_AG_RESV_RMAPBT)->ar_reserved <= pag->pagf_freeblks + pag->pagf_flcount, file: fs/xfs/libxfs/xfs_ag_resv.c, line: 319

[   48.944835]  entry_SYSCALL_64_after_hwframe+0x49/0xbe

Hence we need to ensure the finobt per-ag space reservations take
into account the size of the last AG rather than treat it like all
the other full size AGs.

Note that both refcountbt and rmapbt already take the size of the AG
into account via reading the AGF length directly.
