introduce gsm48_lchan_and_pchan2chan_desc()

The function gsm48_lchan2chan_desc_as_configured() dups
gsm48_lchan2chan_desc() with merely a different pchan type
(ts->pchan_from_config instead of ts->pchan_is).

In an upcoming patch, I would like to do the same, just with yet another
pchan value (derived from lchan->type, because that reflects the channel
type even before a dynamic timeslot switched its pchan type).

So replace gsm48_lchan2chan_desc_as_configured() by
gsm48_lchan_and_pchan2chan_desc() with explicit pchan arg;
also call this from gsm48_lchan2chan_desc(), reducing code dup.

gsm48_lchan2chan_desc_as_configured() had more concise error logging.
Absorb that into the new gsm48_lchan_and_pchan2chan_desc().

Add gsm_lchan_and_pchan2chan_nr(), like gsm_lchan2chan_nr() just with
explicit pchan arg, to be able to pass the pchan down from the new
functions mentioned above.
