P2P: Add optional op_class argument to P2P_SET listen_channel

Browse source 
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.

When specifying a social channel on the 2.4 GHz band (1/6/11) there is
