Seeing frequent segfaults when trying 7.1.x on some production traffic.
What happens is that the MUTEX_TRY_LOCK_FOR segfaults since s->vio.mutex is NULL

Digging into a core dump shows that this happens when s->enabled == 0 and s->error == 1. Inspecting s->vio shows that it's an empty vio instance with a null pointer mutex.
