net: Fix the setting of if_link_state
Link state changes are not dependant on the interface being up, but we also
need to guard against more link state changes being scheduled when the
interface is being detached.
We do this by clearing the link queue but keeping if_link_sheduled = true.
We can check for this in both if_link_state_change() and
if_link_state_change_work() to abort early as there is no point in doing
anything if the interface is being detached because if_down() is called
in if_detach() after the workqueue has been drained to the same overall
effect.
