Wrong paramers usage in Waveform adjustment PLC

The Waveform adjustment PLC defines some parameters twice while their usage is somewhat random which might cause quality deficiency.

The parameters (structure members) under question are as follows:

typedef struct
{
    Word16 Pitch;
    Word16 Pitch_fx;

    Word16 T_bfi;
    Word8 T_bfi_fx;

    Word16 subframe;
    Word16 subframe_fx;

} T_PLCInfo, *T_PLCInfo_HANDLE;
