P2P: Change supplicant scan intervel during WFD session 

During WFD session supplicant scan intervel is one minute. If
there are some saved profiles, then supplicant will issue a scan
for every one minute, this is causing some ping latency in WFD.
Hence supplicant scan intervel should change to five minutes
to improve ping latency in WFD session only.
