mac80211: fix drv_config_iface_filter() behaviour
There are two bugs with this, first, it shouldn't be called on an interface that's down, and secondly, it should then be called when the interface comes up. Note that the currently only user (iwlwifi) doesn't seem to care about either of these scenarios.
