qcacld-3.0: Don't discard nss update when channel bonding is disabled

Browse source 
For STA-DUT, when host receives the beacon forwarded by firmware which
contains NSS update, host discards that beacon if channel bonding is
disabled from INI. This is incorrect behavior.
When channel bonding is disabled from INI and host should discard the
beacon when it contains channel width related updates.
