ALSA oxfw driver allocates memory objects for data specific to some models. These objects are used to maintain functionalities specific to the models for ALSA rawMIDI/control interfaces. They can be released as managed-resource of 'struct snd_card.card_dev'.
This commit uses managed-resource of the sound card device for this purpose.
