qcacld-3.0: Don't disable dfs phyerr offload when no sap/go in DFS ch

According to FW, DFS phyerr offload should be enabled before vdev start,
otherwise FW can't start DFS phyerr offload function.

Do not send DFS phyerr offload disable wmi command before vdev stop, and
FW will handle all the necessary cleanup in vdev stop wmi command.

Without DFS phyerr offload disable wmi command, DFS phyerr offload is
enabled before vdev start.
