Currently, during the VF reset, the VF will send a MBX to inform PF to reset it and the disable command bit will be set whether the MBX is successful. Generally, multiple reset attempts are made after a failure. However, because the command is disabled, all subsequent reset will all fail.
This patch disable the command only after the MBX message is successfully.
