i40e: Move all UDP port notifiers to single function 

This patch goes through and combines the notifiers for VXLAN and GENEVE
into a single function for each action.  So there is now one combined
function for getting ports, one for adding the ports, and one for deleting
the ports.

To compile this driver as a module, choose M here. The module
will be called i40e.

This allows one to create VXLAN virtual interfaces that provide
Layer 2 Networks over Layer 3 Networks. VXLAN is often used
to tunnel virtual network infrastructure in virtualized environments.
Say Y here if you want to use Virtual eXtensible Local Area Network
(VXLAN) in the driver.
