fix: Fix cornor case that segment can't be move out from stopping node (#36431) 

issue: #36426
the old constriant requires only segment on current target can be
balanced, which is wrong, and caused that segment can't be move out from
stopping node, if it's only exist in next target.

by design, stopping balance need to move out all segment on it by
balance task, thus the unfair old constriant should be removed.
