When injecting an exception into a vCPU in Real Mode, suppress the error code by clearing the flag that tracks whether the error code is valid, not by clearing the error code itself. The "typo" was introduced by recent fix for SVM's funky Paged Real Mode.
Opportunistically hoist the logic above the tracepoint so that the trace is coherent with respect to what is actually injected (this was also the behavior prior to the buggy commit).
