mac80211: check fast-xmit on station change
Drivers with fast-xmit (e.g. ath10k) running in AP_VLAN setups would fail to communicate with connected 4addr stations. The reason was when new station associates it first goes into master AP interface. It is not until later that a dedicated AP_VLAN is created for it and the station itself is moved there. After that Tx directed at the station should use 4addr header. However fast-xmit wasn't recalculated and 3addr header remained to be used. This in turn caused the connected 4addr stations to drop packets coming from the AP until some other event would cause fast-xmit to recalculate for that station (which could never come).
