Fix [#31008] IK armature resize goes ugly (Pose mode resize).

This affected legacy solver. Note that even if I don't expect any, this fix *may* break some other IK setups, so animators, please check your IK rigs using legacy solver. ;) Easy to revert if needed, anyway.

Note that iTaSC solver is also buggy with some scaled parent, but here IK'ed bones just can�??t get scaled in any way (either from parent or from there own transformation)... Will try to find what's happenning, though the code is even harder than legacy solver to follow :/
