The vop irq is shared between vop and iommu and irq probing in the
iommu driver moved to the probe function recently. This can in some
cases lead to a stall if the irq is triggered while the vop driver
still has it disabled.
But there is no real need to disable the irq, as the

When some part of bus_set_iommu fails it should undo any made changes
and not simply leave everything as is.
This includes unregistering the bus notifier in iommu_bus_init when
add_iommu_group fails and also setting the bus->iommu_ops back to NULL.
