rtwdev->fw_recovery_work is used to restart hardware when firmware reports
things get abnormal. The calling flow will be 

fw_ recovery_work() -> ... -> rtw_enter_ips() -> rtw_core_stop() ->
cancel_work_sync(&rtwdev->fw_recovery_work)  /* wait for self to finish */


It would be safe to add this cancel_work_sync(&rtwdev->fw_recovery_work)
in rtw_core_deinit()?

So, NACK.
