fm10k: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_port
This change replaces the network device operations for adding or removing a
VXLAN port with operations that are more generically defined to be used for
any UDP offload port but provide a type. As such by just adding a line to
verify that the offload type if VXLAN we can maintain the same
functionality.
