[dpdk-dev] [PATCH] common/iavf: fix arq resource leak

[Qiming Chen <chenqiming_huawei@163.com>]

In the iavf_init_arq function, if an exception occurs in the
iavf_config_arq_regs function, and the previously applied arq bufs
resource is released. This patch maintains the same modification
as the iavf_init_asq function to roll back resources.

Fixes: 87aca6d8d8a4 ("net/iavf/base: fix command buffer memory leak")
