net: mpls: bump maximum number of labels
Allow users to push down more labels per MPLS route. With the previous patches, no memory allocations are based on MAX_NEW_LABELS; the limit is only used to keep userspace in check. At this point MAX_NEW_LABELS is only used for mpls_route_config (copying route data from userspace) and processing nexthops looking for the max number of labels across the route spec.
