config: disable i40e vector driver
Issue: l3fwd app need the ptype in the mbuf to forward the packets properly.
But now some drivers like virtio driver and FVL vPMD will not set the ptype
in mbuf, so l3fwd cannot work properly on that kind of drivers.
Configure the vector PMD option as no for default as a work around for l3fwd.
After the l3fwd app can handle the undefined ptype or the i40e vPMD can
return the ptype, the option will be set as yes for default again.
