KVM: x86: Move "struct kvm_x86_msr_filter" definition to msrs.c

Browse source

Move the definition of "struct kvm_x86_msr_filter" and its associate,
"struct msr_bitmap_range", to msrs.c, as the details of the filters are
very much implementation details that can and should be buried in msrs.c.
While the _existence_ of filters is public knowledge, almost by definition,
the contents don't need to be exposed outside of the MSR 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.

Note, this creates a discrepancy with the PMU event filter structure; that
will be remedied shortly.

No functional change intended.
