ALSA: usb-audio: Remove VALIDATE_RATES quirk for Focusrite devices

Browse source

[ Upstream commit a8cc55bf81 ]

Remove QUIRK_FLAG_VALIDATE_RATES for Focusrite. With the previous
commit, focusrite_valid_sample_rate() produces correct rate tables
without USB probing.

QUIRK_FLAG_VALIDATE_RATES sends SET_CUR requests for each rate (~25ms
each) and leaves the device at 192kHz. This is a problem because that
rate: 1) disables the internal mixer, so outputs are silent until an
application opens the PCM and sets a lower rate, and 2) the Air and
Safe modes get disabled.
