Remove uneeded ms param from alloc_algorithm_func_t func

Since a while ago, the data architecture was changed so that TBF is
guaranteed to always have a MS object associated. Hence, it makes no
sense to pass the MS object as a separate param as we can take it from
tbf object and makes code less confusing.
