Frederic Weisbecker b049340613 vtime: Optimize full dynticks accounting off case with static keys 
If no CPU is in the full dynticks range, we can avoid the full
dynticks cputime accounting through generic vtime along with its
overhead and use the traditional tick based accounting instead.

Let's do this and nope the off case with static keys.
