A pointer to a size_t variable was passed as the void * pointer to
lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value
this caused failure on big-endian hosts.
Avoid this issue in the future by using stw_p() instead. In general we
should use ld*_p() for loading from target memory and st*_p() for
storing to target memory anyway, not the other way around.
Also tighten up a correct use of lduw_p() when stw_p() should be used
instead in virtio_net_get_config().
