You can keep attaching a different new protocol to an HDLC
device until it is brought up.

The HDLC layer calls the protocol ->detach, but the Cisco
HDLC code does not have a detach method.

I'm starting to feel that this is the bug, because as it
stands the Cisco HDLC code leaves stale pointers around
and then if you unload the Cisco HDLC module things can
explode.
