net: hns3: clear VF down state bit before request link status
Currently, the VF down state bit is cleared after VF sending link status request command. There is problem that when VF gets link status replied from PF, the down state bit may still set as 1. In this case, the link status replied from PF will be ignored and always set VF link status to down. To fix this problem, clear VF down state bit before VF requests link status.
