  [tm] fix the visibility of $T_branch_idx in failure route

The bavp's are already available in failure route and they are using the same internal variable for the branch index. So, to keep consistency, the branch index should be visible also in failure route via $T_branch_idx

(cherry picked from commit ae9e51ec131e5d2dd20fc2ac1e28835916a70c7f)
