Maxim Levitsky fe9d9ad89a KVM: Remove subtle "struct kvm_stats_desc" pseudo-overlay

JIRA: https://issues.redhat.com/browse/RHEL-151869

    KVM: Remove subtle "struct kvm_stats_desc" pseudo-overlay

    Remove KVM's internal pseudo-overlay of kvm_stats_desc, which subtly
    aliases the flexible name[] in the uAPI definition with a fixed-size array
    of the same name.  The unusual embedded structure results in compiler
    warnings due to -Wflex-array-member-not-at-end, and also necessitates an
    extra level of dereferencing in KVM.  To avoid the "overlay", define the
    uAPI structure to have a fixed-size name when building for the kernel.

    Opportunistically clean up the indentation for the stats macros, and
    replace spaces with tabs.

    No functional change intended.
