[ALSA] Fix unfreed pnp driver in opti9xx ISA driver
- Added the missing pnp_unregister_card_driver() in the case ISA PnP
isn't found, which caused an error at kobject_add with -EEXIST
Jun 11 09:07:31 rain kernel: kobject_add failed for opti9xx with -EEXIST, don't try to register things with the same name in the same directory.

- Fixed the probe behavior when no PnP is set up. Now it behaves
like the former version.
