This is a preparation patch with no functional change.
Use an enum instead of a boolean for the backend type.
Move the detection logic to the ethdev layer (where it is needed for the
first time).
The virtio_user_dev stores the backend type in the virtio_user_dev
struct so the type is only determined once
