Subject: [PATCH 1/9] staging: r8188eu: simplify the code to prevent scan blinking restart

The code for scan blinking is wrapped into a big if clause to prevent
restarting if scan blinking is already running.

Revert the if condition and exit if scan blinking is running. This does
not change the behaviour.
