KVM: arm/arm64: vgic: Do not cond_resched_lock() with IRQs disabled
To change the active state of an MMIO, halt is requested for all vcpus of the affected guest before modifying the IRQ state. This is done by calling cond_resched_lock() in vgic_mmio_change_active(). However interrupts are disabled at this point and we cannot reschedule a vcpu. We actually don't need any of this, as kvm_arm_halt_guest ensures that all the other vcpus are out of the guest. Let's just drop that useless code.
