xfs: convert xfs_alloc_vextent_iterate_ags() to use perag walker
Source kernel commit: 3432ef6111997f39d2f708dd508159dfaca72942
Now that the AG iteration code in the core allocation code has been
cleaned up, we can easily convert it to use a for_each_perag..()
variant to use active references and skip AGs that it can't get
active references on.
