Before synchronize_irq(), mask the interrupt and clear the raw status, so that the NPU core cannot report a completion afterwards. Do this under job_lock, because the submit path sets the interrupt mask under the same lock. Only touch these registers when the device is powered: check with pm_runtime_get_if_active(), so that a register access with the power domain off cannot raise an SError.
