[PATCH v4 19/30] KVM: x86/pmu: Move "struct kvm_x86_pmu_event_filter" definition to pmu.c

[Sean Christopherson]

Move the definition of "struct kvm_x86_pmu_event_filter" to pmu.c, as the
as the details of the filters are very much implementation details that can
and should be buried in pmu.c.  While the _existence_ of filters is public
knowledge, almost by definition, the contents don't need to be exposed
outside of the PMU code as the filter data is provided by userspace, i.e.
it pretty much has to be dynamically allocated, and thus never should be
fully embedded in a globally visible structure.

No functional change intended
