Keep reference to buffer until it has been replaced
For the code path which uses QWaylandBufferMaterial, the buffer
could potentially be deleted before the material had been
updated, which could cause issues if the render thread was
currently using the textures.
In the default code path this was handled by keeping a reference
to the buffer in the texture provider, but in the alternative YUV
format code path, we did not increase the reference count of the
buffer, so it would be deleted immediately when it was replaced
rather than wait for the sync with the render thread.
