IPoIB: Fix hang in ipoib_flush_paths()

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.

This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1329>.
