[Bug 22034] EXIT_ON_ERROR should use ERR instead of WARN in winealsa.drv

http://bugs.winehq.org/show_bug.cgi?id=22034

The other problem is winealsa.drv hard coded to support
KSDATAFORMAT_SUBTYPE_IEEE_FLOAT in ALSA_supportedFormat

ALSA_ComputeCaps() does not check whether the device support
SND_PCM_FORMAT_FLOAT_LE when wine allow user to modify registry to use "hw"
device which most of them does not support SND_PCM_FORMAT_FLOAT_LE

} else if ((wwo->format.Format.wFormatTag == WAVE_FORMAT_EXTENSIBLE) &&
        IsEqualGUID(&wwo->format.SubFormat, &KSDATAFORMAT_SUBTYPE_IEEE_FLOAT)){
        format = (wwo->format.Format.wBitsPerSample == 32) ?
SND_PCM_FORMAT_FLOAT_LE : -1;
    } else {
        ERR("invalid format: %0x04x\n", wwo->format.Format.wFormatTag);
        retcode = WAVERR_BADFORMAT;
        goto errexit;
    }

if ((err = snd_pcm_hw_params_set_format(pcm, hw_params, format)) < 0) {
        WARN("unable to set required format: %s\n",
snd_pcm_format_name(format));
        EXIT_ON_ERROR( snd_pcm_hw_params_set_format(pcm, hw_params, format),
WAVERR_BADFORMAT, "unable to set required format" );
    }
