KVM: x86: Clean up and document nested #PF workaround
Replace the per-vendor hack-a-fix for KVM's #PF => #PF => #DF workaround
with an explicit, common workaround in kvm_inject_emulated_page_fault().
Aside from being a hack, the current approach is brittle and incomplete,
e.g. nSVM's KVM_SET_NESTED_STATE fails to set ->inject_page_fault(),
and nVMX fails to apply the workaround when VMX is intercepting #PF due
to allow_smaller_maxphyaddr=1.
