qlcnic: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_port

Browse source 
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 is VXLAN we can maintain the same
functionality.

This enables hardware offload support for VXLAN protocol over QLogic's
84XX series adapters.
Say Y here if you want to enable hardware offload support for
Virtual eXtensible Local Area Network (VXLAN) in the driver.
