Current ROC scan will filter probe request. So P2P device cannot receive
probe request. But it is necessary for P2P mode. A P2P device cannot be
discovered if it doesn't respond to others' probe request.

In addition, station won't filter probe request with common scan. But
for station, there is no needed to receive probe request.

Based on the above two points, change scan flag scan_f_filter_prb_req
for QCA6390/WCN6855/QCA2066.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.37
Tested-on: QCA2066 hw2.1 PCI WLAN.HSP.1.1-03926.13-QCAHSPSWPL_V2_SILICONZ_CE-2.52297.2
