ALSA: usb-audio: don't apply interface quirk to Presonus S1824c

Testing with a Presonus STUDIO 1824c together with
a Behringer ultragain digital ADAT device shows that
using all 3 altno settings works fine.

When selecting sample rate, the driver sets the interface
to the correct altno setting and the correct number of
channels is set.

Selecting the correct altno setting via Ardour, Reaper or
whatever other way to set the sample rate is more convenient
than re-loading the driver module with device_setup to
set altno.
