ALSA: usb-audio: Exclude Scarlett 2i2 1st Gen from SKIP_IFACE_SETUP

Browse source

The Focusrite Scarlett 2i2 1st Gen (1235:8006) produces
distorted/silent audio when QUIRK_FLAG_SKIP_IFACE_SETUP is active, as
that flag causes the feedback format to be detected as 17.15 instead
of 16.16.

Add a DEVICE_FLG entry for this device before the Focusrite VENDOR_FLG
entry so that it gets no quirk flags, overriding the vendor-wide
SKIP_IFACE_SETUP. This device doesn't have the internal mixer, Air, or
Safe modes that the quirk was designed to protect.
