[PATCH net] vhost_net: remove VHOST_NET_F_VIRTIO_NET_HDR support
This feature bit is duplicated with VIRTIO_F_ANY_LAYOUT, this means if
a userpsace want to enable VRITIO_F_ANY_LAYOUT,
VHOST_NET_F_VIRTIO_NET_HDR will be implied too. This is wrong and will
break networking. Fixing this by safely removing
VHOST_NET_F_VIRTIO_NET_HDR support. There should be very few or even
no userspace can use this. Further cleanups could be done for
-net-next for safety.
In the future, we need a...

What breaks networking exactly? VHOST_NET supported ANY_LAYOUT
from day one. For this reason it does not need to know about
VRITIO_F_ANY_LAYOUT and we reused the bit for other purposes.
