ppdev: fix PPGETTIME/PPSETTIME ioctls
Going through the uses of timeval in the user space API,
I noticed two bugs in ppdev that were introduced in the y2038
conversion:
* The range check was accidentally moved from ppsettime to
ppgettime
* On sparc64, the microseconds are in the other half of the
64-bit word.
Fix both, and mark the fix for stable backports.
