Revert "ALSA: usb-audio: Add quirk for SmartlinkTechnology M01"

This reverts commit d1aa2b9aad696c0434a5e0ac1d07810ce264e686.

Juan reported that the patch didn't work as expected at the later
check, failing to create PCM capture devices that has worked
beforehand.  Drop the change again for addressing the regression,
and we'll continue developing a proper fix later.
