selftests: fib_tests: sleep after changing carrier

dsahern · davem330 · commit e2ba732a1681 · 2018-02-13T14:34:28.000-05:00
sleep for a second after setting carrier down to allow linkwatch
to propagate the change to the routing stack via netdev_state_change.
As it stands there is a race setting carrier down on the dummy
device and then checking the linkdown flag in the routes.
