Bluetooth: btsdio: Free driver data on SDIO shutdown
Instead of waiting for the hdev object to get freed we now free the private driver-internal data on SDIO shutdown. This allows us to remove the obsolete hci-destruct callback and free our data object right away after calling hci_unregister_dev(). The HCI-core does not call any callbacks after this so we are never called again and can safely exit the module.
