MIPS: KVM: Deliver guest interrupts after local_irq_disable()

Browse Source 
When about to run the guest, deliver guest interrupts after disabling
host interrupts. This should prevent an hrtimer interrupt from being
handled after delivering guest interrupts, and therefore not delivering
the guest timer interrupt until after the next guest exit.
