[dpdk-dev] [PATCH] ethdev: fix compilation related to hairpin

[Ori Kam <orika@mellanox.com>]

This patch solves a compilation issue that is caused due to using
internal function (is_rx_hairpin_queue) inside inline function.

The solution is to remove the usage of the functions
from the burst functions.

Fixes: 60b476d5da3c ("ethdev: add support for hairpin queue")
