qcacmn: Add support to enable strict passive scan
Normally probe request is sent in a passive channel if the
beacon received from the AP. With the strict passive scan
feature, STA doesnot send the probe request even if it
receives beacon from AP.
This can be enabled by using below command.
iwpriv /cfg80211 wifix pas_scanen 1/0
Added a support to send strict passive scan flag to FW in
cfg80211 framework during scan start command.
