mesa: fix format conversion bug in get_tex_rgba_uncompressed()
We need to set the need_convert flag with each loop iteration, not just when the rgba pointer is null. Bug reported by Markus Müller <[email protected]> on mesa-users list. Fixes new piglit arb_texture_float-get-tex3d test. Cc: <[email protected]> Reviewed-by: Anuj Phogat <[email protected]>
