[dpdk-dev] [PATCH] net/i40e/base: fix the resource leakage problem

[chenqiming_huawei at 163.com]

From: Qiming Chen <chenqiming_huawei at 163.com>

In the i40e_init_arq function, when the i40e_config_arq_regs function
returns from processing failure, the previously applied arq_bufs resource
is not released, which leads to leakage.
The patch is processed in the same way as the i40e_init_asq function,
maintaining a unified coding style.

Fixes: 49ea51605be4 ("net/i40e/base: gracefully clean the resources")
