Check the presence of US_FL_BAD_SENSE when assuming US_FL_SANE_SENSE on SPC4+ devices.

However, with recent patch to support UAC3 configuration, second configuration was unintentionally chosen for some of the UAC1/2 devices that had more than one configuration. This was because of the existing check after the audio config check which selected any config which had a non-vendor class. This patch fixes this issue.
