dlm: fix uninitialized variable for search_rsb_list callers
gcc 4.3.0 correctly emits the following warning. search_rsb_list does not *r_ret if no dlm_rsb is found and _search_rsb may pass the uninitialized value upstream on the error path when both calls to search_rsb_list return non-zero error. The fix sets *r_ret to NULL on search_rsb_list's not-found path. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: David Teigland <teigland@redhat.com>
