From: Hongbo Zheng <zhenghongbo3 at huawei.com>
There are coverity defects related "calling
hns3_reset_all_tqps without checking return value
in hns3_do_start".
This patch fixes the warning by add "void" declaration
because here is exception handling, hns3_reset_all_tqps
will have the corresponding error message if it is
handled incorrectly, so it is not necessary to check
hns3_reset_all_tqps return value, here keep ret as the
error code causing the exception.
Coverity issue: 363048
Fixes: fa29fe45a7b4 ("net/hns3: support queue start and stop")
