mac80211: fix configure_filter invocation after stop
Since configure_filter can sleep now, any multicast
configuration needed to be postponed to a work struct.
This, however, lead to a problem that we could queue
the work, stop the device and then afterwards invoke
configure_filter which may lead to driver hangs and is
a bug. To fix this, we can just cancel the filter work
since it's unnecessary to do after stopping the hw.
Since there are various places that call drv_stop, and
two of them do very similar things, the code for them
can be put into a shared function at the same time.
