staging: rtl8712: Make return of 0 explicit

Delete unnecessary local variable whose value is always 0 and
return 0 as the result.

The following Coccinelle script was used:

@@
identifier ret; expression E;
type T;
@@
(
- T ret;
|
- T ret = 0;
)

... when != \(ret=E
\|ret--\|ret++\|--ret\|++ret\|ret-=E\|ret+=E\|ret|=E\|ret&=E\)
(
?-ret = 0;
)
... when != \(ret=E
\|ret--\|ret++\|--ret\|++ret\|ret-=E\|ret+=E\|ret|=E\|ret&=E\)
(
return
- ret
+ 0
;
)
