[dpdk-dev] [PATCH] net/thunderx: fix memory leak when allocate rbdr desc ring fails

[wangyunjian]

From: Yunjian Wang <wangyunjian at huawei.com>

In nicvf_qset_rbdr_alloc(), we allocate memory for the 'rbdr'
structure but not released when allocate 'rbdr desc ring' fails.

Fixes: 7413feee662d ("net/thunderx: add device start/stop and close")
