KVM: nVMX: Refactor PMU refresh to avoid referencing kvm_x86_ops.pmu_ops
Refactor the nested VMX PMU refresh helper to pass it a flag stating
whether or not the vCPU has PERF_GLOBAL_CTRL instead of having the nVMX
helper query the information by bouncing through kvm_x86_ops.pmu_ops.
This will allow a future patch to use static_call() for the PMU ops
without having to export any static call definitions from common x86, and
it is also a step toward unexported kvm_x86_ops.
Alternatively, nVMX could call kvm_pmu_is_valid_msr() to indirectly use
kvm_x86_ops.pmu_ops, but that would incur an extra layer of indirection
and would require exporting kvm_pmu_is_valid_msr().
Opportunistically rename the helper to keep line lengths somewhat
reasonable, and to better capture its high-level role.
No functional change intended.
