KVM: SVM: Document that vCPU ID == APIC ID in AVIC kick fastpatch
Document that AVIC is inhibited if any vCPU's APIC ID diverges from its
vCPU ID, i.e. that there's no need to check for a destination match in
the AVIC kick fast path.
Opportunistically tweak comments to remove "guest bug", as that suggests
KVM is punting on error handling, which is not the case. Targeting a
non-existent vCPU or no vCPUs _may_ be a guest software bug, but whether
or not it's a guest bug is irrelevant. Such behavior is architecturally
legal and thus needs to faithfully emulated by KVM (and it is).
