KVM: Move vcpu alloc and init invocation to common code

Now that all architectures tightly couple vcpu allocation/free with the mandatory calls to kvm_{un}init_vcpu(), move the sequences verbatim to common KVM code. Move both allocation and initialization in a single patch to eliminate thrash in arch specific code. The bisection benefits of moving the two pieces in separate patches is marginal at best, whereas the odds of introducing a transient arch specific bug are non-zero.
