From: Zhigang Gong <zhigang.gong at linux.intel.com>
We need to put current front_buffer to back buffer thus we
don't need to create a new back buffer next time. This behaviou
should be the same with or without glamor. Previous code
incorrectly discard the previous front_buffer and cause a
big buffer leak problem.
