Robert Shearman a3e948e83a mpls: validate L2 via address length 
If an L2 via address for an mpls nexthop is specified, the length of
the L2 address must match that expected by the output device,
otherwise it could access memory beyond the end of the via address
buffer in the route.

This check was present prior to commit f8efb73c97 ("mpls: multipath
route support"), but got lost in the refactoring, so add it back,
applying it to all nexthops in multipath routes.
