765ca516069a40e2ea7081997a508892db084c8e virtio-scsi: don't lock AioContext around virtio_queue_aio_attach_host_notifier()
virtio_queue_aio_attach_host_notifier() does not require the AioContext
lock. Stop taking the lock and add an explicit smp_wmb() because we were
relying on the implicit barrier in the AioContext lock before.
