drm/vblank: Fix vblank timestamp debugs
We're currently calling ktime_to_timespec64() on stack garbage
hence the debug output for vblank timestamps also contains garbage.
Let's assing something to the ktime_t first before we go converting
it to a timespec.
While at it micro-optimize the ktime_to_timespec64() calls away
when vblank debugging isn't enabled.
Fixes: 67680d3c0464 ("drm: vblank: use ktime_t instead of timeval")
