Subject: [PATCH v2] staging: lustre: lustre: obdclass: Modify return statement

Modify the return statement.
The Coccinelle semantic patch used to make this change is as follows:

@@
expression e, ret;
@@

-ret =
+return
        e;
-return ret;

Delete the declaration of the return variable rc, as it is no longer used.
