[dpdk-dev] [PATCH] net/fm10k: fix memory leak when thresh check fails

[wangyunjian <wangyunjian@huawei.com>]

From: Yunjian Wang <wangyunjian@huawei.com>

In fm10k_rx_queue_setup(), we allocate memory for the queue
structure but not released when thresh check fails.

Fixes: 6cfe8969c969 ("fm10k: add Rx queue setup/release")
