ospf6d: fix missing intra-area-prefix-LSA after a graceful restart

Upon exiting the GR mode, force reorigination of intra-area-prefix-LSAs
on all attached areas. This is to ensure all configured areas will have
an associated intra-area-prefix-LSA at the end of the GR procedures,
even if the area doesn't have any full adjacency.
