[ Upstream commit 29838144f280fc03ca06a621568f34e1d0a65a4f ]

The logic of this function was accidentally broken by a checkpatch
inspired cleanup.  I've modified the code to restore the original
behavior and also make checkpatch happy.

Fixes: 98fe05e21a6e ("staging: rtl8712: Remove unnecesary else after return statement.")
