KVM: PPC: Book3S HV: Fix machine check delivery to guest
The code that delivered a machine check to the guest after handling
it in real mode failed to load up r11 before calling kvmppc_msr_interrupt,
which needs the old MSR value in r11 so it can see the transactional
state there. This adds the missing load.
