ipoib_flush_paths() can hang during an SM up/down loop: if path_rec_start() fails (for instance, because there is no sm_ah), the path is still added to the path list by neigh_add_path(). Then, ipoib_flush_paths() will wait for path->done, but it will never complete because the request was not issued at all. Fix this by completing path->done if issuing the query fails.
