staging: wilc1000: Remove useless return variables

This patch removes unnecessary return variables and compresses the
return logic.
The coccinelle script that finds and fixes this issue is:

@@ type T; identifier i,f; constant C; @@
- T i;
...when != i
when strict
( return -C;
|
- i =
+ return
f(...);
- return i;
)
