net/enic: reset VXLAN port regardless of overlay offload

Browse Source 
Currently, the driver resets the vxlan port register only if overlay
offload is enabled. But, the register is actually tied to hardware
vxlan parsing, which is an independent feature and is always enabled
even if overlay offload is disabled. If left uninitialized, it can
affect flow rules that match vxlan. So always reset the port number
when HW vxlan parsing is available.
