android: camera_device: Fix crash in calling CameraDevice::close()
The problem is happening because we seem to add a CameraStream associated buffer (depending on the CameraStream::Type) to the Request, in CameraDevice::processCaptureRequest(). However, when the camera stops, all the current buffers are marked with FrameMetadata::FrameCancelled and proceed to completion. But the buffer associated with the CameraStream (that was previously added to the request) has now been cleared out with a part of streams_.clear(), even before the camera stop() has been invoked. Any access to those request buffers after they have been cleared, will result in a crash.
