fs/cifs: keep guid when assigning fid to fileinfo
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.
