Subject: [PATCH net] net: hns3: make sure ptp clock is unregister and freed if hclge_ptp_get_cycle returns an error

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

During the initialization of ptp, hclge_ptp_get_cycle might return an error
and returned directly without unregister clock and free it. To avoid that,
call hclge_ptp_destroy_clock to unregist and free clock if
hclge_ptp_get_cycle failed.
