audio/dsound: replace custom logging with error_report & trace
The DirectSound audio backend uses its own logging infrastructure (AUD_log, AUD_vlog, dolog) and the AUDIO_CAP macro. This approach is inconsistent with the rest of QEMU and makes the output harder to filter and configure. Replace the custom logging with standard QEMU error reporting.
