Staging: rtl8192u: Remove unnecessary variable

This patch detects the cases in which a variable is not modified through
the code and it is used as a return value. The variable is detected and
removed by coccinelle using the following semantic patch:

@@ type T; expression expr; identifier r; constant c; @@

-T r = expr;
... when != r
    when strict
-return r;
+return expr;
