l1sap.c: fn_ms_adj: Add err logging and always return GSM_RTP_DURATION
After latest changes, l2 expects to receive an event for every TCH
frame, that is, no TCH frame event should be lost on that layer. We
should now then be safe returning always GSM_RTP_DURATION.
The code which used to calculate the variable duration is left there to
assert that indeed we are not longer having this kind of issues.
