Subject: net: hns3: log and clear hardware error after reset complete
Patch-mainline: v5.5-rc1
Git-commit: 4fdd0bca6152aa201898454e63cbb255a18ae6e9
References: bsc#1154353

When device is resetting, the CMDQ service may be stopped until
reset completed. If a new RAS error occurs at this moment, it
will no be able to clear the RAS source. This patch fixes it
by clear the RAS source after reset complete.
