[dpdk-dev] [PATCH] ethdev: fix rte_eth_dev_owner_unset

The rte_eth_dev_owner_unset function is unusable because
it always returns -EINVAL. This is because the magic (unowned)
value is flagged as not valid.
Move the validation of owner into set and unset as
separate calls.
Fixes: 5b7ba31148a8 ("ethdev: add port ownership")
