Subject: [PATCH net-next 05/12] net: hns3: fix a -Wformat-nonliteral compile warning

From: Yonglong Liu <liuyonglong@...wei.com>

When setting -Wformat=2, there is a compiler warning like this:

hclge_main.c:xxx:x: warning: format not a string literal and no
format arguments [-Wformat-nonliteral]
strs[i].desc);
^~~~

This patch adds missing format parameter "%s" to snprintf() to
fix it.

Fixes: 46a3df9f9718 ("Add HNS3 Acceleration Engine & Compatibility Layer Support")
