If MMIO emulation fails we don't want to crash the whole guest by
returning to userspace.

The original commit bbf45ba57eae ("KVM: ppc: PowerPC 440 KVM
implementation") added a todo:

  /* XXX Deliver Program interrupt to guest. */

and later the commit d69614a295ae ("KVM: PPC: Separate loadstore
emulation from priv emulation") added the Program interrupt injection
but in another file, so I'm assuming it was missed that this block
needed to be altered.
