[PATCH 09/10] staging: r8188eu: simplify error handling for missing station

[Martin Kaiser <martin@kaiser.cx>]

Simplify the code to handle the case where we're associated to a station
that is not in our list of known stations.

We can simply exit in this case. This patch reverts the if-condition and
saves one level of indentation.
