virtio: don't set VIRTIO_NET_HDR_F_DATA_VALID on xmit



This patch part reverts fd2a0437 and e858fae2 which introduced a
subtle change in how the virtio_net flags are derived from the SKBs
ip_summed field.

With the above commits, the flags are set to VIRTIO_NET_HDR_F_DATA_VALID
when ip_summed == CHECKSUM_UNNECESSARY, thus treating it differently to
ip_summed == CHECKSUM_NONE, which should be the same.

Further, the virtio spec 1.0 / CS04 explicitly says that
VIRTIO_NET_HDR_F_DATA_VALID must not be set by the driver.

Fixes: fd2a0437 ("virtio_net: introduce virtio_net_hdr_{from,to}_skb")
Fixes: e858fae2 (" virtio_net: use common code for virtio_net_hdr and skb GSO conversion")
