Sergio Lopez 6329219749 vm-virtio: queue: Use a SeqCst fence on get_used_event ...

On x86_64, a hint to the compiler is not enough, we need to issue a
MFENCE instruction. Replace the Acquire fence with a SeqCst one.

Without this, it's still possible to miss an used_event update,
leading to the omission of a notification, possibly stalling the
vring.
