[dpdk-dev] [PATCH] ethdev: add function name to log message

[Stephen Hemminger <stephen@networkplumber.org>]

While debugging some virtio driver issues, saw:
	Invalid port_id=3
but it was not clear which function was logging this because the
same log is being done in multiple places in ethdev.

Trivial fix is to prefix with function name as is done in other
drivers.
