commit ddfd9c5fd2236c426aead743cc884898fde24f5e
Author: Alex Loiko <aleloi@webrtc.org>

Fix AudioProcessing fuzzer crash.

When audio_processing_fuzzer runs with 'DCHECK_ALWAYS_ON', it crashes
when both AEC and AECM is enabled at the same time. This change
detects that case and fixes
https://clusterfuzz.com/v2/testcase-detail/6389429496446976.

It also removes an unnecessary safeguard that didn't allow fuzzing
with 8kHz input signals.
