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.
