Geoffrey D. Bennett 020b6b0dc7 ALSA: usb-audio: scarlett2: Improve driver startup messages
commit 265d1a90e4fb6d3264d8122fbd10760e5e733be6 upstream.

Add separate init function to call the existing controls_create
function so a custom error can be displayed if initialisation fails.

Use info level instead of error for notifications.

Display the VID/PID so device_setup is targeted to the right device.

Display "enabled" message to easily confirm that the driver is loaded.
