sound: oxygen: make the owner module a parameter of the probe function

Move the owner field out of the oxygen_model structure and make it
a parameter of oxygen_pci_probe(), because the actual owner module does
not depend on the card model.  Furthermore, moving it out of the model
structure allows us to create the card structure before the actual model
is known.
