Change subject: Clarify frame loss counter for l1sched_chan_state
......................................................................

Clarify frame loss counter for l1sched_chan_state

Each logical channel (e.g. SACCH, SDCCH, etc.) has a counter of
lost L2 frames. Let's use a bit better name for it, and correct
its description in the 'l1sched_chan_state' struct definition.
