[PATCH] eventdev/eth_rx: fix return of rx adapter instance get

[Shijith Thotton <sthotton@marvell.com>]

The API to get rx adapter instance is returning error for event devices
with internal port capability and eth_rx_adapter_instance_get op
undefined. But as the Rx adapter is internally maintaining the queue
information needed to find the instance id, event devices can opt out
from defining the op. Modified code to match this logic.

Fixes: a1793ee8aba0 ("eventdev/eth_rx: add adapter instance get API")
