Takashi Iwai 9f0fb11264 usb: gadget: midi2: Fix incorrect default MIDI2 protocol setup
commit 3eb27d3e32c78badbc4db6ae76614b5961e32291 upstream.

The MIDI2 gadget driver handled the default MIDI protocol version
incorrectly due to the confusion of the protocol version passed via
configfs (either 1 or 2) and UMP protocol bits (0x100 / 0x200).
As a consequence, the default protocol always resulted in MIDI1.

This patch addresses the misunderstanding of the protocol handling.
