ALSA: usb-audio: Remove redundant workaround for Roland quirk
The recent fix for the delayed card registration made the current
workaround for QUIRK_AUTODETECT superfluous, since the card
registration itself is delayed until the last interface probe.
This patch drops the redundant workaround in
create_autodetect_quirks() for simplification.
