From: Eric Dumazet <eduma...@google.com>
fib_lookup() forces FIB_LOOKUP_NOREF flag, while fib_table_lookup()
does not.
This patch solves the typical message at reboot time or device
dismantle :
unregister_netdevice: waiting for eth0 to become free. Usage count = 4
Fixes: 3bfd847203c6 ("net: Use passed in table for nexthop lookups")
