Bluetooth: Improve *_get() functions to return the object type
It's natural to have *_get() functions that increment the reference count of an object to return the object type itself. This way it's simple to make a copy of the object pointer and increase the reference count in a single step. This patch updates two such get() functions, namely hci_conn_get() and l2cap_conn_get(), and updates the users to take advantage of the new API.
