qcacld-2.0: Fix AP+AP MCC OBSS scan unreliable
AP1 starts on 2.4g, AP2 starts on 5g ht40.
The AP2 is always failed to find the interference
AP during OBSS scan. It is because the cld driver
uses passive scan but the dwell time is set to
active scan's default dwell time 80ms. That is too
short for passive scan.
The fix is to set the dwell time based on scan type.
