drm/vblank: Use abs64(diff_ns) for s64 diff_ns instead of abs(diff_ns)
Use of abs() wrongly wrapped diff_ns to 32 bit, which gives a 1/4000
probability of a missed vblank increment at each vblank irq reenable
if the kms driver doesn't support high precision vblank timestamping.
Not a big deal in practice, but let's make it nice.
