Sujith Manoharan 48bf43fad7 ath9k: Fix beacon processing in offchannel 
When interfaces of different types are present
in a context and an offchannel request is received
on a STA interface, we end up trying to process
beacons received when we are offchannel. This hits
the below warning since offchannel will not have proper
beacon parameters.

Fix this by not processing beacons received when we
are offchannel.
