vmx: reset virtio queue state on device reset
when a virtio device gets reset, we have to also reset the device
shadow indices: availableidx and usedidx. for extra safetly,
we also reset the buffer descriptor table addresses.
this is accomplished by adding a vioqreset(VIOQueue*) function
that brings the queue to its initial reset state.
this fixes non functional ethernet after reboot(8).
