KVM: PPC: booke: rework rescheduling checks
Instead of checking whether we should reschedule only when we exited due to an interrupt, let's always check before entering the guest back again. This gets the target more in line with the other archs. Also while at it, generalize the whole thing so that eventually we could have a single kvmppc_prepare_to_enter function for all ppc targets that does signal and reschedule checking for us.
