qcacld-3.0: Fix invalid operating class calculation during channel switch

Browse source 
Fix invalid operating class calculation while sending out channel switch
frames. The operating class is getting wrongly calculated using the
channel width instead of the channel offset. Fix this by calculating and
passing the channel offset parameter instead of the channel width to the
necessary function to ensure that the operating class gets calculated
correctly.
