renderer-native: Don't leak DMA buffer CoglFramebuffer
When we created the DMA buffer backed CoglFramebuffer, we handed it over to CoglDmaBufHandle which took its own reference. What we failed to do was to release our own reference to it, effectively leaking it. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1283
