openvswitch: Use regular VXLAN net_device device
This gets rid of all OVS specific VXLAN code in the receive and transmit path by using a VXLAN net_device to represent the vport. Only a small shim layer remains which takes care of handling the VXLAN specific OVS Netlink configuration. Unexports vxlan_sock_add(), vxlan_sock_release(), vxlan_xmit_skb() since they are no longer needed.
