From: Stanislaw Kardach <k...@semihalf.com>
rte_pci_device and rte_eth_dev are process-local structures. Therefore
ena_adapter::pdev and ena_adapter::rte_dev cannot be used universally.
Switch this to extracting those structures via rte_eth_devices indexing
and remove pdev since it's not used outside of init.
