ice/ptp: fix crosstimestamp reportingdev-queue
Set use_nsecs=true as timestamp is reported in ns. Lack of this result
in smaller timestamp error window which cause error during phc2sys
execution on E825 NICs:
phc2sys[1768.256]: ioctl PTP_SYS_OFFSET_PRECISE: Invalid argument
Before commit "Provide infrastructure for converting to/from a base clock"
the parameter use_nsec was not required. "Remove convert_art_to_tsc()"
rework shall already contain use_nsecs=true.
Testing hints (ethX is PF netdev):
phc2sys -s ethX -c CLOCK_REALTIME -O 37 -m
phc2sys[1769.256]: CLOCK_REALTIME phc offset -5 s0 freq -0 delay 0
Fixes: d4bea547ebb57 ("ice/ptp: Remove convert_art_to_tsc()")
Fixes: 6b2e29977518e ("timekeeping: Provide infrastructure for converting to/from a base clock")
