net: hns3: fix VF wrong speed and duplex issue
If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode
when PF queries the port information from firmware.
After imp reset command is executed, PF status changes to down,
and PF will query link status and updates port information
from firmware in a periodic scheduled task.
However, there is a low probability that port information is updated
when PF is down, and then PF link status changes to up.
In this case, PF synchronizes incorrect rate and duplex mode to VF.
This patch fixes it by updating port information before
PF synchronizes the rate and duplex to the VF
when PF changes to up.
