ptp: Pass hwtstamp to ptp_convert_timestamp()
ptp_convert_timestamp() converts only the timestamp hwtstamp, which is a field of the argument with the type struct skb_shared_hwtstamps *. So a pointer to the hwtstamp field of this structure is sufficient. Rework ptp_convert_timestamp() to use an argument of type ktime_t *. This allows to add additional timestamp manipulation stages before the call of ptp_convert_timestamp().
