[PATCH] virtio-net: fix inconsistent legacy header size

["Michael S. Tsirkin" <mst@redhat.com>]

Current text says:
	The legacy driver only presented num_buffers in the struct
	virtio_net_hdr when VIRTIO_NET_F_MRG_RXBUF was not negotiated;

Should be:
	"... was negotiated ..." instead of "... was not negotiated ..."

To be consistent with the following:
	without that feature the structure was 2 bytes shorter.

I'm checking this in under the trivial corrections rule.
