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())
