[dpdk-dev] [PATCH 3/7] net/hns3: remove redundant code about mbx

["Min Hu (Connor)" <humin29@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

Some mbx messages do not need to reply with data. In this case,
it is no need to set the response data address and the response
length.

This patch removes these redundant codes from mbx messages that do
not need be replied.

Fixes: a5475d61fa34 ("net/hns3: support VF")
