If firmware crashes during FW probing it would try
to perform FW recovery which uses mac80211
workqueue before registering to mac80211.

Using internal workqueue solves the problem.

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
