wlcore: Allow stopping fw log in recovery
The FW panic log is read during recovery work. It has to be stopped properly before reading. otherwise, inconsistent data might be read which cause the driver to freeze. __wlcore_cmd_send has to work for the special case of CMD_STOP_FWLOGGER, while in recovery, in order to stop the fw log before it is read.
