[PATCH 1/3] staging: r8188eu: don't restart "no link" blinking unnecessarily

[Martin Kaiser]

Simplify one of the cases in rtw_led_control. If we're already blinking
because we have no link, we don't have to restart this blinking when the
caller requests it again. We can simply return and keep on blinking.
