[dpdk-dev] [PATCH 21.05] net/virtio: remove duplicate port id from virtio_user

[David Marchand <david.marchand@redhat.com>]

The private virtio_user_dev structure embeds a virtio_hw which itself
contains the ethdev port_id.
Make use of it and remove the duplicate port_id field.

Signed-off-by: David Marchand <david.marchand@redhat.com>

Posting this cleanup that I caught when reviewing/discussing the port_id
fix from Maxime.
It can wait 21.05.
