[Qemu-devel] [PATCH 3/3] xen: flush queue when getting an event |

xen does not have a register that, when written, will cause can_receive
to go from false to true. However, flushing the queue can be attempted
whenever the front-end raises its side of the Xen event channel. There
is a single event channel for tx and rx.
