4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Aurelien Aptel <[email protected]> commit 94f873717571c759b7928399cbbddfa3d569bd01 upstream. When we open a durable handle we give a Globally Unique Identifier (GUID) to the server which we must keep for later reference e.g. when reopening persistent handles on reconnection. Without this the GUID generated for a new persistent handle was lost and 16 zero bytes were used instead on re-opening.
