Fix T71213: Mask or Mirror before Armature breaks weight paint.

This is a revert of a small fraction of commit rB5e332fd700
that introduced the issue according to bisect.

Doing a break here is wrong, because BKE_crazyspace_build_sculpt
assumes that processing stopped at the first deform modifier
without deformMatrices, and thus skips all modifiers until it
finds one like that. Thus this early loop exit makes the behavior
worse, as instead of skipping just Mask and Mirror, it skips all.
