net/hns3: fix PTP interrupt logging

PMD driver will receive a PTP interrupt when receive a PTP packet.
But driver doesn't distinguish it. As a result, many unknown events
are printed when many PTP packets are received on the link. The PTP
interrupt is normal, so this patch doesn't log and ignores it.
