P2P: Prefer U-NII-3 over U-NII-1 during channel selection

Browse source 
Some devices disable use of U-NII-1 (channels 36-48) for P2P due to it
being indoor use only in number of locations. If U-NII-3 (channels
149-161) is available, try to pick a channel from that range first
during random channel selection to reduce likelihood of interoperability
issues.
