staging: lustre: Remove unnecessary return capture

Instead of storing the return value of a function call into a variable and then returning it, we can club the two into a single return statement. This change was made using the following semantic patch by Coccinelle:

@@
local idexpression ret;
expression e;

(quoted diff) +1 -2

-ret =
+return
     e;
-return ret;
