staging: r8188eu: remove state checks in rtw_led_control

There's no need to check for bSurpriseRemoved or bDriverStopped in the
rtw_led_control function. This function schedules a delayed worker which
calls SwLedOn or SwLedOff (or the function calls SwLedOff directly).

SwLedOn and SwLedOff check bDriverStopped themselves or they initiate a
USB control transfer via usb_write, where bSurpriseRemoved is checked.
