Switch the MPLS blocks for RTM_CHANGE. Do not always remove the MPLS
information if the gateway changes, since real MPLS routes need to
change gateway and outgoing label on topology changes. So if there is
MPLS information and an outgoing label do a proper change but if the
gateway of a non-MPLS route is changed remove the MPLS path since it is
no longer valid.
