P2P: Use 'type=progressive' while calling P2P_FIND to discover peer

The current behavior of P2P_FIND with no additional arguments will start
one full channel scan followed by only social channel scans. If GO is
operating in not social channel and due to some reason the first full
channel scan is not able to discover GO, subsequent social channel scans
will fail to discover GO.

Adding 'type=progressive' while sending P2P_FIND will insure to scan one
non-social channel (different channel in each iteration) along with
social channels and eventually the GO will be discovered.
