Revert "Camera2: create new streams if surface size has changed"

This change is redundant after the following change is merged:

Camera2: Handle surface size change

When comparing if two OutputConfigurations are equal, also check
the width, height, format, dataspace when the output configurations
were created. With this, CameraDeviceImpl knows that the surface has
changed sizes and will reconfigure the stream.
