perf/x86/intel: Make @data a mandatory param for intel_guest_get_msrs()
Drop "support" for passing a NULL @data/@kvm_pmu param when getting guest
MSRs. KVM, the only in-tree user, unconditionally passes a non-NULL
pointer, and carrying code that suggests @data may be NULL is confusing,
e.g. incorrectly implies that there are scenarios where KVM doesn't pass
a PMU context.
