net/mlx5: Use provided clock ID for history snapshot

Browse Source 
The PTP core indicates in system_device_crosststamp::clock_id the clock ID
for which the system time stamp should be taken. That allows to utilize
hardware timestamps with e.g. AUX clocks.

Use ktime_get_snapshot_id() and hand the provided clock ID in.

No functional change.
