netdev-dpdk: Remove 'error' from non error log.

netdev-dpdk: Remove 'error' from non error log.

Presently, if OVS tries to setup more queues than
are allowed by a specific NIC, OVS will handle
this case by retrying with a lower amount of queues.

Rather than reporting initial failed queue setups
in the logs as ERROR, they are reported as INFO but
contain the word 'error'. Unless a user has detailed
knowledge of OVS-DPDK workings, this is confusing.

Let's remove 'error' from the INFO log.
