staging: rtl8712: Remove unnecessary variables

Remove unnecessary variables that can be replaced with a single line of code.

The semantic patch used to find this is:

// <smpl>
@@
expression ret;
@@
- if (ret) return ret;
- return 0;
+ return ret;

@@
local idexpression ret;
expression e;
@@
- ret = e;
- return ret;
+ return e;

@@
type T;
identifier i;
expression E;
@@
- T i = E;
 ... when != i

@@
type T;
identifier i;
@@
- T i;
 ... when != i
// </smpl>
