ao_wasapi: log return code when probing audio formats

We log a large number of formats, but we rarely log the result of the
probing. Change this.

The logic in try_format_exclusive() changes slightly, but should be
equivalent. EXIT_ON_ERROR() checks for FAILED(), which should be
exclusive to SUCCEEDED().
