I recall that things used to work with or without modifiers at some
point. That was basically the point of the "pitch-linear by default"
patch, see:

    https://gitlab.freedesktop.org/mesa/mesa/-/commit/9603d81df05105857b676f20dff964ef3ab0ecff

If we don't force pitch-linear for cases where we don't have modifiers,
there's no way we can properly display these as framebuffers because we
lack the modifier information at the kernel level.
