main/format: skip format conversion if src and dst format are equal
Fixes 'KHR-GL45.copy_image.functional' on Nouveau and i965. v2: (by Kenneth Graunke) Rewrite patch according to Jason Ekstrand's review feedback. This makes it handle differing strides, which i965 needed. Signed-off-by: Karol Herbst <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
