mesa: Skip redundant texture completeness checking during image validation.

Browse source 
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.
