[PATCH net-next 11/11] net: hns3: add exception handling when enable NIC HW error interrupts

[Huazhong Tan]

From: Weihang Li <liweihang@xxxxxxxxxxxxx>

If we failed to enable NIC HW error interrupts during client
initialization in some cases, we should do exception handling to clear
flags and free the resources.

Fixes: 00ea6e5fda9d ("net: hns3: delay and separate enabling of NIC and ROCE HW errors")
