qcacld-3.0: Follow concurrent SAP switch channel in the same band

When lte channel avoidance event triggered, multiple SAP will choose
safe channel from pcl/acs combination and switch to the safe channel
one by one.

Actually when force SCC mode is enabled, if one SAP is the same band
as other concurrent SAP whose channel is already safe, it doesn't
need to choose safe channel from pcl/acs again, just needs to
follow concurrent SAP channel. Add code to implement this policy.
