net: ena: Pass ena_adapter instead of net_device to ena_xmit_common()
This change will enable the ability to use ena_xmit_common() in functions that don't have a net_device pointer. While it can be retrieved by dereferencing ena_adapter (adapter->netdev), there's no reason to do it in fast path code where this pointer is only needed for debug prints.
