net: Flush local routes when device changes vrf association
The VRF driver cycles netdevs when an interface is enslaved or released:
the down event is used to flush neighbor and route tables and the up
event (if the interface was already up) effectively moves local and
connected routes to the proper table.
As of 4f823defdd5b the local route is left hanging around after a link
down, so when a netdev is moved from one VRF to another (or released
from a VRF altogether) local routes are left in the wrong table.
Fix by handling the NETDEV_CHANGEUPPER event. When the upper dev is
an L3mdev then call fib_disable_ip to flush all routes, local ones
to.
Fixes: 4f823defdd5b ("ipv4: fix to not remove local route on link down")
