Reference shm pool for destroyed buffers
Currently, if an application is closed, all of its shm buffers will be destroyed. However, the compositor may want to access them to fade out the window. With this change, the underlying shm pool will be referenced when a shm buffer is destroyed. So, the compositor can access buffer data even if the buffer is destroyed.
