qcacmn: Use active scan request for P2P Device mode

During scan request from framework wlan_cfg80211_scan gets
invoked. If the cfg80211_scan_request parameter has number
of ssids set to zero then driver will set the scan mode to
passive mode. This will result in fw doing passive scan
instead of active scan. Probe request will not be sent to
discover the peer. This will sometimes result in failure
to discover P2P GO peer.

Set the scan mode to active mode in scan request message to FW.
