[dpdk-dev] [PATCH v3] ethdev: silence error message on rte_eth_dev_owner_unset

Subject: [PATCH 1/5] ethdev: silence error message on rte_eth_dev_owner_unset

The rte_eth_dev_owner_unset function always generates a log
message because the unset value for owner id is 0.

Also, when rte_eth_dev_owner_delete is called with a valid
owner id, the log message should be at NOTICE not ERROR
severity.

Fixes: 5b7ba31148a8 ("ethdev: add port ownership")
