mesa: Skip redundant texture completeness checking during image validation.
The call to _mesa_test_texobj_completeness() is unnecessary if the texture is already known to be complete. If the texture object is dirtied in the meantime _BaseComplete and _MipmapComplete will be reset to false. _mesa_is_image_unit_valid() will start to be called more frequently in a future commit, so it seems desirable to avoid the unnecessary work.
