Sticking a cleanup there as well is good insurance, but it seems like a
reasonable policy to drop references when values go 'out of scope' as
they do in cleanup_plane_fb. But, you're right, we only *need* to drop
the reference in the destroy function, it's just that the state hangs
around until the next mode setting operation, which is likely to be days
away.
