Subject: [PATCH V3 net 4/7] net: hns3: release PTP resources if pf initialization failed

From: Peiyang Wang <wangpeiyang1@...wei.com>

During the PF initialization process, hclge_update_port_info may return an
error code for some reason. At this point,  the ptp initialization has been
completed. To void memory leaks, the resources that are applied by ptp
should be released. Therefore, when hclge_update_port_info returns an error
code, hclge_ptp_uninit is called to release the corresponding resources.
