mncc: Select the codec similar to the modify handling 

In case the default TCH/F codec is "EFR" and we do an early
assignment from SDCCH to a TCH we would assign the TCH/H
codec. This is because the lchan_type will be neither a
TCH/H nor a TCH/F.

At the same time the _gsm48_lchan_modify code to check for
half vs. full-rate is the other way around. Align both.

It is full-rate if it is not a TCH_H. This will have some
other complications down the way (early assignment on
cells with only TCH/H). So the mode should not depend on
the _current_ channel but the kind of channel we want.
