Bjorn Volcker f6a99e63b6 Refactor audio_processing: Free functions return void
There is no point in returning an error when Free() fails. In fact it can only happen if we have a null pointer as object. There is further no place where the return value is used.

Affected components are
- aec
- aecm
- agc
- ns
