This fixes issue with interface bridging.
Linux bridging sets promiscuous mode for all
interfaces that are in a bridge. This translates
to configure_filter() being called in a mac80211
driver.
Before the patch operational interface would be
started and upped again when promiscuous mode was
enabled causing all sorts of strange issues:
* no HTT RX happening (i.e. no traffic)
* FW crash upon driver reload/unload
