USB: flush outstanding URBs when suspending
This patch (as989) makes usbcore flush all outstanding URBs for each device as the device is suspended. This will be true even when CONFIG_USB_SUSPEND is not enabled. In addition, an extra can_submit flag is added to the usb_device structure. That flag will be turned off whenever a suspend request has been received for the device, even if the device isn't actually suspended because CONFIG_USB_SUSPEND isn't set. It's no longer necessary to check for the device state being equal to USB_STATE_SUSPENDED during URB submission; that check can be replaced by a check of the can_submit flag. This also permits us to remove some questionable references to the deprecated power.power_state field.
