af: improve filter chain setup retry limit
af_reinit() is responsible for inserting automatic conversion filters for channel remixing, format conversion, and resampling. We don't require that a single filter can do all these (even though af_lavrresample does nearly all of this, sometimes af_format has to be used instead for format conversions). This makes setting up the chain more complicated, and a way is needed to prevent endless appending of conversion filters if a conversion is not possible. Until now, this used a stupidly simple yet robust static retry limit to detect failure. This is perfectly fine, and the limit (20) was good enough to handle about ~5 filters. But with more filters, and if each filter requires 3 additional conversion filters, this would fail. So raise the limit to 4 retries per filter. This is still stupidly simple and robust, but won't arbitrarily fail if the filter count is too large.
