[Intel-wired-lan] [PATCH iwl-net] ice/ptp: Fix reporting of crosstimestamp

[Anton Nadezhdin]

Set use_nsecs=true as timestamp is reported in ns. Lack of this result
in smaller timestamp error window which case error during phc2sys
execution on some platforms:
phc2sys[1768.256]: ioctl PTP_SYS_OFFSET_PRECISE: Invalid argument

Previously function convert_art_to_tsc was converting ts to the cycles
instead of ns.

Testing hints (ethX is PF netdev):
phc2sys -s ethX -c CLOCK_REALTIME  -O 37 -m

Fixes: d4bea547ebb57 (ice/ptp: Remove convert_art_to_tsc())
