usbcore: Select only first configuration for non-UAC3 compliant devices
In most of the UAC1 and UAC2 audio devices, the first configuration is most often the best configuration. 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.
