Subject: [PATCH net-next 07/12] net: hns3: not reset TQP in the DOWN while VF resetting

Since the hardware does not handle mailboxes and the hardware
reset include TQP reset, so it is unnecessary to reset TQP
in the hclgevf_ae_stop() while doing VF reset. Also it is
unnecessary to reset the remaining TQP when one reset fails.
