vnc: qemu can die if the client is disconnected while updating screen
agraf reported that qemu_mutex_destroy(vs->output_mutex) while failing
in vnc_disconnect_finish().
It's because vnc_worker_thread_loop() tries to unlock the mutex while
not locked. The unlocking call doesn't fail (pthread bug ?), but
the destroy call does.
