KVM: nVMX: Do not report error code when synthesizing VM-Exit from Real Mode
Don't report an error code to L1 when synthesizing a nested VM-Exit and
L2 is in Real Mode. Per Intel's SDM, regarding the error code valid bit:
This bit is always 0 if the VM exit occurred while the logical processor
was in real-address mode (CR0.PE=0).
The bug was introduced by a recent fix for AMD's Paged Real Mode, which
moved the error code suppression from the common "queue exception" path
to the "inject exception" path, but missed VMX's "synthesize VM-Exit"
path.
Fixes: b97f07458373 ("KVM: x86: determine if an exception has an error code only when injecting it.")
