[DLM] Fix spin lock already unlocked bug
[DLM] Fix spin lock already unlocked bug

I just noticed this message when testing some other changes I'd made to
lowcomms (to use workqueues) but the problem seems to be in the current
git trees too. I'm amazed no-one has seen it.

    BUG: spinlock already unlocked on CPU#1, dlm_recoverd/16868
