[RFC PATCH v1 40/42] kvm: x86: use kvm_vcpu scheduling-state accessors and struct stat fields

[Sriram Nambakam <snambakam@linux.microsoft.com>]

Finish the conversion begun by the kvm_vcpu_common rework: read
wants_to_run through kvm_vcpu_wants_to_run() and account statistics via
the embedded vcpu->stat.* fields (not the removed vcpu->stat-> pointer)
in the SVM and nested-VMX paths.
