xfs: update the pag for the last AG at recovery time
Currently log recovery never updates the in-core perag values for the
last allocation group when they were grown by growfs. This leads to
btree record validation failures for the alloc, ialloc or finotbt
trees if a transaction references this new space.
Found by Brian's new growfs recovery stress test.
