dpdk: don't automatically whitelist vmxnet3 PCI interfaces

If no PCI address is specified in dpdk config, the default to automatically
put all PCIs in the whitelist.
For vmxnet3 PCIs, we want to change its default to exclude the vmxnet3 PCIs.
That is to put them in the blacklist instead of whitelist.
