Fix for crashes observed with scaled inputs in LTV test 

[x] Fixes issue for:
+10dB
	1 ISM with metadata bitrate switching from 13.2 kbps to 128 kbps, 32 kHz in, 32 kHz out, EXT out, DTX on
-10dB
	4 ISM with and without extended metadata bitrate switching from 24.4 kbps to 256 kbps, 48 kHz in, 48 kHz out, DTX on, EXT out
	4 ISM with and without metadata bitrate switching from 24.4 kbps to 256 kbps, 48 kHz in, 48 kHz out, DTX on, HOA3 out

[x] Changes done in Q for generate_comfort_noise_dec_hf_ivas_fx and vas_ism_param_dec_tc_gain_ajust_fx updated with additional checks.
