ptp: Switch to ktime_get_snapshot_id() for pre/post timestamps

Browse source

To prepare for a new PTP IOCTL, which exposes the raw counter value along
with the requested system time snapshot, switch the pre/post time stamp
sampling over to use ktime_get_snapshot_id() and fix up all usage sites.

No functional change intended.

The ptp_vmclock conversion was simplified by David Woodhouse.
