Subject: ALSA: firewire-motu: destroy stream data surely at failure of card initialization

From: Takashi Sakamoto <o-takashi@sakamocchi.jp>

commit dbd7396b4f24e0c3284fcc05f5def24f52c09884 upstream.

When failing sound card registration after initializing stream data, this
module leaves allocated data in stream data. This commit fixes the bug.
