[PATCH] ptp: replace getnstimeofday64() with ktime_get_real_ts64()

[PATCH] ptp: replace getnstimeofday64() with ktime_get_real_ts64()

[Arnd Bergmann]

getnstimeofday64() is deprecated and getting replaced throughout
the kernel with ktime_get_*() based helpers for a more consistent
interface.

The two functions do the exact same thing, so this is just
a cosmetic change.
