ice/ptp: fix crosstimestamp reporting
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
This problem was introduced in the cited commit which omitted setting
use_nsecs to true when converting the ice driver to use
convert_base_to_cs().
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
