P2P: Allow all channels for multi-channel concurrency (no negotiation)

Browse source 
Commit 79879f4ae8 enabled all channels to
be used when negotiating channel with a driver that supports
multi-channel concurrency. Extend that to cover cases where the channel
is not being negotiated (e.g., p2p_group_add to start a GO).
