P2P: Do not stop Listen state if it is on correct channel

Browse source 
This is needed to optimize response to GO Negotiation Request frames.
The extra remain-on-channel cancel followed by new remain-on-channel for
the same channel takes too much time with some driver/firmware
designs for the response to go out quickly enough to avoid peer
timing out while waiting for our response.
