VMX requires a properly set instruction length VM entry field when
trying to inject soft exception and interrupts. We have to preserve this
state across VM save/restore to avoid breaking the re-injection of such
events on Intel. So add it to the new VCPU event state.
Can't we fake it? set instruction length to 1 and rewind rip by 1.
The only case where I think this can fail is if we have a fault during
the soft exception injection.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
