ath6kl: reconfigure RSN capabilities when restarting AP
If the firmware decides to initiate a channel switch on an AP vif running an RSN BSS, reconfigure the saved RSN IE capabilities as well. Fixes a bug where the beacon and 4-way handshake would have a capability mismatch after a channel switch, since the firmware apparently clears these on an AP disconnect.
