[gegl] seamless-clone: max-refine-steps is not used.

[Jehan Pagès <jehanp src gnome org>]

commit 346139b4fb9d2ce9fe5de89ecb4f74e23cb50286
Author: Jehan <jehan girinstud io>
Date:   Sun Apr 27 22:27:07 2014 +1200

    seamless-clone: max-refine-steps is not used.
    
    Make it max-refine-scale instead, whose default value is 5
    (making default behavior unchanged).
