KVM: x86/pmu: Clean up vPMU comments and stray blank lines
Tidy up the x86 vPMU emulation code and its selftests by fixing comments
that no longer reflect the code along with assorted spelling and grammar
mistakes, and by dropping redundant blank lines reported by checkpatch.
No functional change intended.
