[PATCH 03/14] ALSA: usb-audio: scarlett2: Coding style improvements

[Geoffrey D. Bennett]

Improve alignment and readability with:
- Whitespace fixes
- Add leading zeros to 32-bit flag values
- Rename SCARLETT2_USB_GET_METER_LEVELS to SCARLETT2_USB_GET_METER
- Rename SCARLETT2_PORT_DIRECTIONS to SCARLETT2_PORT_DIRNS
