Tweak to early threaded update escape

Issue was caused by some objects being in bMain and tagged
for update but not being in the DAG. This means objects
wouldn't be updated and their recalc flag remains untouched
triggering threaded for the next frame.

Solved by tweaking POST_UPDATE_HANDLER_WORKAROUND in the way
that it checks objects' recalc flags from the DAG, not from
the bMain. This will work a bit longer since DAG stored more
nodes than objects in the scene, but this code only runs in
cases when there're some objects tagged for update, which
keeps overall CPU usage on such a workaround pretty low.

Now CPU usage on 11a_comp scene from project Pampa went down
from ~15% down to ~5% (2,69 release uses ~%7).
