[Cluster-devel] dlm: Fix comment in dlm.h regarding lock_dlm() return values

[Steven Whitehouse]

The code in dlm_lock() explicitly tests for a return value of
-EAGAIN and changes it to zero in that case, so this function
can never return -EAGAIN. I'm not 100% sure that it can
return -ENOTCONN either, but the code paths are more tricky
to trace in that case, so I've left that one for now.
