ucm: return error if boot_list is empty

[GitHub pull_request - opened]

alsa-project/alsa-lib pull request #94 was opened from jason77-wang:

If bootlist is empty, that means there is no BootSequence defined
in the ucm for this sound card, let set_boot_user() return error,
then alsactl could have chance to use non-ucm ways to initialize the
sound card.
