ath6kl: Fix target assert in p2p bringup with multi vif
Using interface 0 for p2p causes target assert. This is because interface 0 is always initialized to non-p2p operations. Fix this issue by initializing all the interfaces for p2p when fw is capable of dynamic interface switching. When fw is not capable of dynamic switching, make sure p2p is not brought up on interface which is not initialized for this purpose.
