> There's no need to wait until a completion is received to unmap
> TX descriptor buffers that have been passed to the hypervisor.
> Instead unmap it when the hypervisor call has completed. This patch
> avoids the possibility that a buffer will not be unmapped because
> a TX completion is lost or mishandled.
