This makes several minor cleanups to these functions:
* Follow usual convention of an early exit on error, rather than having
most of the body in an if
* Clearer naming of cpu and cpu_. Now callcpu is the cpu from which the
RTAS call is invoked, newcpu is the cpu which we're starting
* Use cpu_synchronize_state() instead of kvm_cpu_synchronize_state()
directly
* Remove pointless comment describing what cpu_synchronize_state() does
* Use ppc_store_lpcr() instead of directly writing the register field
