Bluetooth: discard bt_sock_unregister() errors
After we successfully registered a socket via bt_sock_register() there is
no reason to ever check the return code of bt_sock_unregister(). If
bt_sock_unregister() fails, it means the socket _is_ already unregistered
so we have what we want, don't we?
Also, to get bt_sock_unregister() to fail, another part of the kernel has
to unregister _our_ socket. This is sooo _wrong_ that it will break way
earlier than when we unregister our socket.
