[PATCH 3/6] staging: r8188eu: remove bLedNoLinkBlinkInProgress

[Martin Kaiser]

Remove the bLedNoLinkBlinkInProgress state variable. Its sole purpose is
to block subsequent requests for "no link" blinking when this blinking
pattern is already active.

It's perfectly safe to restart "no link" blinking. We can remove
bLedNoLinkBlinkInProgress and the many places where it's updated.
