[dpdk-stable] [dpdk-dev] [PATCH] efd: fix tailq entry leak in error path

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

In rte_efd_create() allocated memory for tailq entry, we should
free it when error happens, otherwise it will lead to memory leak.

Fixes: 56b6ef874f80 ("efd: new Elastic Flow Distributor library")
