ALSA: ump: Set default protocol when not given explicitly
[ Upstream commit bc42ca002d5d211f9c57334b9b4c25ddb0b4ec35 ]
When an inquiry of the current protocol via UMP Stream Configuration
message fails by some reason, we may leave the current protocol
undefined, which may lead to unexpected behavior. Better to assume a
valid protocol found in the protocol capability bits instead.
For a device that doesn't support the UMP v1.2 feature, it won't reach
to this code path, and USB MIDI GTB descriptor would be used for
determining the protocol, instead.
