[dpdk-dev] [PATCH] ethdev: handle removed device properly on promisc replay

[Andrew Rybchenko]

Promiscuous mode callback may return error if the device is removed.
Use eth_err() helper to check the condition and return appropriate
error code.

Fixes: dff6d544fb3c ("ethdev: do nothing if promiscuous mode is applied again")
