ms_need_dl_tbf(): Fix state checks and document function

A new state TBF_ST_WAIT_REUSE_TFI was added lately in dl_tbf_fsm, which
allows differentiating the time where the MS is listening on PACCH
after having sent last DL ACK/NACK, and time where it should already be
in idle mode.
In the former, the ms_need_dl_tbf() should return false since the MS is
still ongoing in packet-active mode (and new data incoming from SGSN
will trigger new DL TBF assignment over PACCH as needed), while in the
later we want to start a new PCH assignment.
