Staging: rtl8188eu: Remove parentheses around right side an assignment

Parentheses are not needed around the right hand side of an assignment.
This patch remove parenthese of such occurenses. Issue was detected and
solved using the following coccinelle script:

@rule1@
identifier x, y, z;
expression E1, E2;
@@

(
x = (y == z);
|
x = (E1 == E2);
|
 x =
-(
...
-)
 ;
)
