aft: Reorder global static variables of aft.c.

These variables constitute the state of the audio file table. The
overall logic is easier to understand if they are combined at one
spot at the top of the file.

The definition of struct ls_data needs to be moved up because of
this. Pure code movement, no semantic changes.
