Check task_state of instance before volume actions
Check task_state before verify resize or before detachment. We need to make sure the task_state moved out from resize_finish before we trigger some action like attach/detach volume. So when we update flvor and volume at the samethime, the resize action will not affect volume attachment/detachment.
