Roland Dreier 6ef190cc92 IPoIB: Fix crash when path record fails after path flush ... Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") changed how paths are flushed on an SM event. This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.
