qcacmn: Disable radar for current channel before selecting new channel

In current implementation, after radar detection, a new channel is selected
and then radar is disabled on the new channel. The new channel may be a DFS
channel and radar will be disabled on the new channel.

Radar disable should be called for the current channel and not on the new
channel. Therefore, disable the radar first and then select the new
channel.
