qcacmn: Fix host dfs confirmation FR issues

1. Do not send the RADAR found command to FW for bangradar. Since FW is
   unaware of the bangradar command for Partial Offload chips there is no
   need to send the Radar found indication to FW in bangradar processing.

2. Fix two times vap restart during spoof test: After sending the radar
   found command to the FW, the host waits for the FW to send the status
   check event to the host but if FW takes a very long time to send the
   event then the host timer times out and restarts the channel. After the
   channel restart if the host receives the status from FW, the host does
   the channel change again. Increase the host timer timeout value to avoid
   the two times channel change.

3. When removing the spoofed-radar-infected channel from NOL list, also
   remove the channel from regulatory channel list so that the regulatory
   channels are consistent with NOL.
