ApplyFdCng_ivas_fx() called twice

The function ApplyFdCng_ivas_fx() is called twice in a row in the ACELP core decoder at https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/blob/main/lib_dec/acelp_core_dec_ivas_fx.c#L691 and https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/blob/main/lib_dec/acelp_core_dec_ivas_fx.c#L705 differing only in some scalings in between.

This looks suspicious to me and should be reviewed to determine whether one of the calls should not be removed.
