[GFS2] Fix ordering bug in lock_dlm
This looks like a lot of change, but in fact its not. Mostly its things moving from one file to another. The change is just that instead of queuing lock completions and callbacks from the DLM we now pass them directly to GFS2. This gives us a net loss of two list heads per glock (a fair saving in memory) plus a reduction in the latency of delivering the messages to GFS2, plus we now have one thread fewer as well. There was a bug where callbacks and completions could be delivered in the wrong order due to this unnecessary queuing which is fixed by this patch.
