[PATCH] staging: rtl8188eu: core: rtw_mlme: Removed variables that is never used

[Rickard Strandqvist]

Variable was assigned a value that was never used.
I have also removed all the code that thereby serves no purpose.

This was found using a static code analysis program called cppcheck

Nope.

And delete the "len = 0" line as well.

Rickard, these are too many patches and you didn't think about them
carefully enough.  I'm not reviewing the rest.
