RDMA/hns: Fix VF triggering PF reset in abnormal interrupt handler 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IAMO4D



----------------------------------------------------------------------

In abnormal interrupt handler, a PF reset will be triggered even if
the device is a VF. It should be a VF reset.

Fixes: 2b9acb9a ("RDMA/hns: Add the process of AEQ overflow for hip08")
