Subject: [PATCH] staging: r8188eu: remove bLedLinkBlinkInProgress

Remove the bLedLinkBlinkInProgress component from struct led_priv. Its
only use is to block requests for "link blinking" when this blinking
pattern is already active.

The "link blinking" pattern is a continuous blinking pattern (as opposed
to other patterns where we blink N times), it's no problem to restart this
pattern when it's already running.
