net: hns3: add vf fault process in hns3 ras

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I63AH1


CVE: NA

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

Currently hns3 driver supports vf fault detect feature. Several ras caused
by VF resources don't need to do PF function reset for recovery. The driver
only needs to reset the specified VF.

So this patch adds process in ras module. New process will get detailed
information about ras and do the most correct measures based on these
accurate information.
