netdev-dpdk: Print netdev name for txq mapping.

In case of reconfiguration while 'vhost_id' is not set yet,
there will be the meaningless message like:

    |netdev_dpdk|DBG|TX queue mapping for
    |netdev_dpdk|DBG| 0 -->  0

It's better to print the name of the netdev which is always set.

Additionally fixed possible splitting by other log messages and
missing space in the queue state message.
