qcacld-3.0: Correct channel parameters during channel switch notification
Correct the channel parameters that are calculated and used to indicate the channel switch notification sent to user space. The channel bonding values should not be used to get the channel width information since they can be used only in STA mode to enable or disable the channel bonding. Fix the same by getting the updated channel switch information from the session entries. Change-Id: Ia51779cddb2b9c3108b211822f104c45f88e53fd CRs-Fixed: 1021380
