[PATCH v2 2/4] kvm/ppc/booke64: Fix lazy ee handling in kvmppc_handle_exit()

[Scott Wood]

EE is hard-disabled on entry to kvmppc_handle_exit(), so call
hard_irq_disable() so that PACA_IRQ_HARD_DIS is set, and soft_enabled
is unset.

Without this, we get warnings such as arch/powerpc/kernel/time.c:300,
and sometimes host kernel hangs.
