drm/radeon/kms: r600/r700 don't process IRQ if not initialized In some rare case the wptr returned from the hw wasn't 0 and leaded to trick r600_process_irq that their were irq to process. Add a check to bail out if irq hasn't been initialized this will avoid oops provoqued by the rare wptr != 0 on initialization.
