qcacld-2.0: Set channel BW as 20 MHz for IBSS in 2.4 GHz
When IBSS is started in 2.4 GHz, it uses CBW40 by default.
But the device doesn't support VHT40 in 2.4G for STA/IBSS as
there is no support in firmware to do OBSS scan.
Update cbmode as 20 MHz if the device is in IBSS mode and is
operating in 2.4 GHz.
