net: mpls: Don't show nexthop if device has been deleted ...
If the device for a nexthop in a multipath route is deleted, the nexthop
is effectively removed from the route. Currently, a route dump still
returns the nexhop though without the device set:
$ ip -f mpls ro ls
100
nexthopvia inet 10.11.1.2 dev br0
nexthopvia inet 10.100.3.1 dev eth3
$ ip li del br0
$ ip -f mpls ro ls
100
nexthopvia inet 10.11.1.2 dev * dead linkdown
nexthopvia inet 10.100.3.1 dev eth3
Since the nexthop is effectively deleted, drop the hop from the route
dump.
