kvm: Simplify cpu_synchronize_state()

Browse source 
cpu_synchronize_state() is a little unreadable since the 'modified'
argument isn't self-explanatory.  Simplify it by making it always
synchronize the kernel state into qemu, and automatically flush the
registers back to the kernel if they've been synchronized on this
exit.
