ath9k: Fix interface combinations for multi-channel concurrency
ath9k: Fix interface combinations for multi-channel concurrency

drivers. So advertise these features only when the driver is not
supporting channel context and modparam "use_chanctx" is introduced
for preparing channel context support in ath9k.
