iPXE fails if DPDK enabled

[NiKiZe]

The message "Common virtio capability not found!\n"
is only shown due to that you have DEBUG=virtio enabled at compile time, and it fails to initialize a Virtion 1.01 device
It is not an error in itself.
Does it fail to also initialize the legacy virtio device as well?

The question becomes what is the actual issue you are having, as in: is it something that doesn't work?
