For very long, we have kept this pointer back to the per-cpu

Recent investigations have shown that this pointer is easy
to abuse in preemptible context, which is a sure sign that
it would better be gone. Not to mention that a per-cpu
pointer is faster to access at all times.
Helps to make the references to `kvm_host_data` clearer with there now
being just one way to get to it and shows that it is scoped to the
current CPU. A good change IMO!
Thanks! Can I take this as a Reviewed-by or Acked-by tag? Just let me
know.
Cheers,
M.
