qcacld-3.0: Switch channel when radar is found in dfs channel

When radar is found, the current channel is put in NOL list and the state
is set as CHANNEL_STATE_DISABLE.

Currently if channel state is not CHANNEL_STATE_DFS, it will not do channel
change. This is not correct.

Do channel change when radar is found in dfs channel
