xfs: remove xfs_rmap_ag_owner and friends

Browse Source 
Owner information for static fs metadata can be defined readonly at
build time because it never changes across filesystems.  This enables us
to reduce stack usage (particularly in scrub) because we can use the
statically defined oinfo structures.
