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.
