From: Chengchang Tang <tangchengch...@huawei.com>
Currently, when dump the queue interrupt registers, the number of
registers that should be dumped is calculated from num_msi. But the
value of num_msi includes the number of misc interrupts. So, for some
hardware version, like kupeng930, it will lead to an illegal access.
This patch replace num_msi with intr_tqps_num which indicate the
number of interrupts used by the tqps.
Fixes: 936eda25e8da ("net/hns3: support dump register")
