qcacld-3.0: Fix CSA handling to the same channel
Currently CSA event is ignored if the new channel is same as
current channel and there is no check for the BW comparison.
CSA can be done to the same channel with different BW. Allow the
CSA processing with same channel if the CSA has the different BW
