[PATCH 10/13] staging: rtl8192e: make return of 0 explicit

[Julia Lawall]

From: Julia Lawall <Julia.Lawall@xxxxxxx>

Delete unnecessary use of a local variable to immediately return 0.

A simplified version of the semantic patch that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
local idexpression ret;
expression e;
position p;
@@

-ret = 0;
... when != ret = e
return 
- ret
+ 0
  ;
// </smpl>
