KVM: x86: Tweak the code and comment related to handling concurrent NMIs

Browse source

Tweak the code and comment that deals with concurrent NMIs to explicitly
call out that x86 allows exactly one pending NMI, but that KVM needs to
temporarily allow two pending NMIs in order to workaround the fact that
the target vCPU cannot immediately recognize an incoming NMI, unlike bare
metal.

No functional change intended.
