vhost-user: Add MTU protocol feature and op
This patch implements VHOST_USER_PROTOCOL_F_NET_MTU
protocol feature and VHOST_USER_NET_SET_MTU request so
that the backend gets notified of the user defined host
MTU.
If backend supports VHOST_USER_PROTOCOL_F_REPLY_ACK,
QEMU assumes MTU is valid if success is returned.
Vhost-net driver sends this request through a new
vhost_net_set_mtu vhost_ops entry.
