xfs: introduce xfs_ag_shrink_space()
This patch introduces a helper to shrink unused space in the last AG
by fixing up the freespace btree.
Also make sure that the per-AG reservation works under the new AG
size. If such per-AG reservation or extent allocation fails, roll
the transaction so the new transaction could cancel without any side
effects.
