[PATCH] virtio_net: lower limit on buffer size

commit d85b758f72b0 "virtio_net: fix support for small rings" was supposed to increase the buffer size for small rings but had an unintentional side effect of decreasing it for large rings. This seems to break some setups - it's not yet clear why, but increasing buffer size back to what it was
