xfs: bump up reserved blocks in xfs_alloc_set_aside
Setting aside 4 blocks globally for bmbt splits isn't all that useful,
as different threads can allocate space in parallel. Bump it to 4
blocks per AG to allow each thread that is currently doing an
allocation to dip into it separately. Without that we may no have
enough reserved blocks if there are enough parallel transactions
in an almost out space file system that all run into bmap btree
splits.
