Avoid transmitting on the wrong CPU

The transmit and receive rings have DPCs and event channels affinitized
to a particular CPU. Thus, when XENNET queues a new packet at the
transmit side, make sure the packet is prepared and posted from the
CPU to which the DPC and event channel are bound to avoid lock contention.
