mpls: Send route delete notifications when router module is unloaded
[ Upstream commit e37791ec1ad785b59022ae211f63a16189bacebf ]
When the mpls_router module is unloaded, mpls routes are deleted but
notifications are not sent to userspace leaving userspace caches
out of sync. Add the call to mpls_notify_route in mpls_net_exit as
routes are freed.
