qcacld-3.0: select min bw during csa if channel bonding disabled

Browse source 
During CSA max bw is selected for SAP in STA + SAP concurrency
for non-dfs channel and SAP is tear down after 60 sec of operation
due to STA is in 20Mhz and SAP is in 40Mhz with
IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag disabled.

This change is to select 20Mhz BW during CSA if channel bonding is
disabled.
