Michael Olbrich 44f36b9b55 libweston: don't return buffers early with multiple backends 
Releasing the buffer reference here works because the backend has seen the
surface and has updated keep_buffer if necessary. With multiple backends
the assumption breaks. The same surface may be visible (now or later) on an
output from another backend. This backend has not seen the buffer yet so it
cannot update keep_buffer.
As a result, the reference is released to early. A surface that is rendered
on a secondary backend first can no longer be placed on a plane on a DRM
backend.

To avoid this, always keep the buffer reference until it is replaced when
multiple backends are involved.
