ALSA: usb-audio: Allow Focusrite devices to use low samplerates

Commit 05f254a6369ac020fc0382a7cbd3ef64ad997c92 ("ALSA: usb-audio:
Improve filtering of sample rates on Focusrite devices") changed the
check for max_rate in a way which was overly restrictive, forcing
devices to use very high samplerates if they support them, despite
support existing for lower rates as well.

This maintains the intended outcome (ensuring samplerates selected are
supported) while allowing devices with higher maximum samplerates to be
opened at all supported samplerates.

This patch was tested with a Clarett+ 8Pre USB
