Subject: [PATCH 3/5] ntp: use timespec64 in sync_cmos_clock

The sync_cmos_clock has one use of struct timespec, which we want to
eventually replace with timespec64 or similar in the kernel. There
is no way this one can overflow, but the conversion to timespec64
is trivial and has no other dependencies.
