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.
