[dpdk-stable] [dpdk-dev] [PATCH] baseband/turbo_sw: fix memory leak in error path

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

In q_setup() allocated memory for the queue data, we should free
it when error happens, otherwise it will lead to memory leak.

Fixes: b8cfe2c9aed2 ("bb/turbo_sw: add software turbo driver")
