staging: lustre: ptlrpc: remove unused variable

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

This patch removes a variable that was simply used to
store the return value of a function call before
returning it.

The issue was detected and resolved using the following
coccinelle script:

@@
identifier len,f;
@@

-int len;
 ... when != len
     when strict
-len =
+return
        f(...);
-return len;
