FST: Fix dialog token wrap-around

Browse source 
Dialog token is only 8 bits and maintaining u32 version of it in struct
fst_group resulted in incorrect wrap-around behavior in
fst_group_assign_dialog_token(). It was possible to assign u8
dialog_token value 0 because of this. Fix this by using u8 variable
consistently.
