staging: lustre: remove extra parentheses around left bit shift operations 

Author: Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>

Removes extra parentheses around bitwise left shift operations.
The cases handled here are when resultant values are assigned to
variables. The issue was detected and resolved using the following
coccinelle script:

@@
expression e, e1;
constant c;
@@

e =
-(e1
+e1
<<
-c);
+c;

@@
identifier i;
constant c;
type t;
expression e;
@@

t i =
-(e
+e
<<
-c);
+c;

@@
expression e, e1;
identifier f;
constant c;
@@

e1 = f(...,
-(e
+e
<<
-c)
+c
,...);
