P2P: Add optional op_class argument to P2P_SET listen_channel

The existing implementation in p2p_ctrl_set used a hard-coded operating
class 81 which is only suitable for the social channels in the 2.4 GHz
band, and will not work for the social channel in the 60 GHz band.
Extend this by adding an optional op_class argument to P2P_SET
listen_channel. If not specified, use the default value of 81 to match
existing behavior.

 Set P2P Listen channel. This is mainly meant for testing purposes and
 changing the Listen channel during normal operations can result in
 protocol failures.
