Subject: net/mlx5: Update ptp_clock_event foreach PPS event
Patch-mainline: v4.15-rc9
Git-commit: afc98a0b46d8576a55f18092400cc518d03a79a1
References: bsc#1075020
PPS event did not update ptp_clock_event fields, therefore,
timestamp value was not updated correctly. This fix updates the
event source and the timestamp value for each PPS event.
Fixes: 7c39afb394c7 ("net/mlx5: PTP code migration to driver core section")
