[PATCH net-next 07/15] igb: use ktime_get_real helpers in igb_ptp_reset()

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Aleksandr Loktionov <aleksandr.loktionov@intel.com>

Replace ktime_to_ns(ktime_get_real()) with the direct equivalent
ktime_get_real_ns() and ktime_to_timespec64(ktime_get_real()) with
ktime_get_real_ts64() in igb_ptp_reset().  Using the combined helpers
makes the intent clearer.
