cosmetic: dyn ts init: undup logging for gprs = none
Reshuffle the decision not to activate PDCH when GPRS is off:
Even though all current callers should avoid passing a PDCH activation in case
GPRS is off, it's a better idea to not assert on it and crash osmo-bsc.
Move the decision to omit PDCH activation and logging about it into the actual
functions that do PDCH activation. If PDCH activation is skipped, the lchan
then just stays as it was, and that's what it should anyway be doing.
