Revert "ALSA: usb-audio: Drop superfluous interface setup at parsing"
This reverts commit ac5e2fb425e1121ceef2b9d1b3ffccc195d55707. The commit caused a regression on Behringer UMC404HD (and likely others). As the change was meant only as a minor optimization, it's better to revert it to address the regression.
