KVM: nVMX: Add a helper to identify low-priority #DB traps
Add a helper to identify "low"-priority #DB traps, i.e. trap-like #DBs
that aren't TSS T flag #DBs, and tweak the related code to operate on any
queued exception. A future commit will separate exceptions that are
intercepted by L1, i.e. cause nested VM-Exit, from those that do NOT
trigger nested VM-Exit. I.e. there will be multiple exception structs
and multiple invocations of the helpers.
No functional change intended.
