trxcon/sched_trx.c: fix: omit inactive logical channels

The sched_frame_clck_cb() is responsible for UL burst transmission.
Iterating over each timeslot, it chooses a proper lchan handler
according to a current frame number and a multiframe layout in use,
takes a L2 UL frame from a TX buffer, and finally calls the chosen
handler in order to to encode and transmit a taken frame.

A handler should be called only for activated logical channels...
but for some long time, there was a bug, so each lchan was
processed, including inactive ones. It's time to fix this.
