Subject: [PATCH net-next 08/11] net: hns3: Add missing break in misc_irq_handle

From: Yunsheng Lin <linyunsheng@...wei.com>

There is a break missing in the switch/case handling in
hclge_misc_irq_handle, which causes the log to output
uncorrectly.

This patch adds the missing break, and change the dev_dbg
to dev_warn in order to better catch the error.

Fixes: c1a81619d73a ("net: hns3: Add mailbox interrupt handling to PF driver")
