Staging: rtl8192e: rtl8192e: Merge two lines and remove unused variable

This patch merges an assignment with an immediately following return of
the assigned variable. It also removes variables that became unused due to this transformation.
The following Coccinelle semantic patch was used to make this transformation:

@r@
identifier ret;
identifier f;
@@

-ret =
+return
     f(...);
-return ret;

@@
identifier r.ret;
expression e1;
type t;
@@

(
-t ret = e1;
|
-t ret;
)
 ... when != ret
     when strict
