sched: Pass the current TS to the control create functions

Currently the checks in that function are based on the different
internal TS values of a TBF. It is assumed that they match the TS
that the current RTS refers to.

This commit adds a TS parameter to create_ul_ass, create_dl_ass,
and create_ul_ack to make this more explicit.
