try to avoid infinite recalc loop.

try to avoid infinite recalc loop.

as reported, elicity triggers an infinite loop by calling
edje_object_part_geometry_get(), which in turns calls
_edje_recalc_do() which in turns calls the elicit code that requests
edje_object_part_geometry_get() and since it's still marked as
"dirty", it enters the loop...

the real fix is just the move of ed->dirty = 0; before calling
recalcs, but I also unmarked object as need_recalculate so we can even
avoid requesting object to recalculate from evas.
