ALSA: usb-audio: don't log messages meant for 1810c when initializing 1824c

The log messages for the PreSonus STUDIO 1810c about
device_setup are not applicable to the 1824c, and should
not be logged when 1824c initializes.

Refactor from if statement to switch statement as there
might be more STUDIO series devices added later.
