[non-be] Resolve #1033: Memory leak in OMASA to BINAURAL with HRTF with bitrate switching

• Related issues: #1033 (closed)
• Requested reviewers:

Reason why this change is needed

TD-renderer HRTF data loaded from a HRTF binary file is erroneously free'd during bitrate switching reconfigure.

Description of the change

In the decoder bitrate-change related reconfigurations, do not free the TD-renderer HRTF data.

Affected operating points

Renderer-only change.

All bitstreams are BE.

Output may be changed in the case when TD-renderer + HRTF binary file + bitrate switching is used (OMASA, MC)
