net/enic: reset VXLAN port during initialization

Browse Source 
The NIC persists the vxlan port number across vNIC init/de-init
(e.g. restart testpmd). So, explicitly reset the setting to the
default value (4789) as part of the initialization.

Fixes: 8a4efd1741 ("net/enic: add handlers to add/delete vxlan port number")
