net/hns3: fix VF reset on mailbox failure

Browse Source 
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.
