staging: r8188eu: remove BlinkingLedState

Both bLedOn and BlinkingLedState in struct led_priv store the same
information.

The boolean bLedOn stores the curent led state while BlinkingLedState
stores the next led state to be set during blinking, which is the inverse
of the current led state. (The led is either off or blinking, it's never
continuously on.)

This patch removes BlinkingLedState and uses bLedOn instead.

The LED_BLINK_WPS_STOP case in blink_work checked for
pLed->BlinkingLedState != RTW_LED_ON. This is true if the next led
blinking state is ON, i.e. if the led has just been switched off by
blink_work, i.e. if (!pLed->bLedOn).
