[Samba] Veto Op Locks does not seem to working properly after updates

[Mark Bannister]

Continuation of this thread: 
https://www.spinics.net/lists/samba/msg179456.html

I was able to get Samba working (properly I think) except my database 
cannot properly lock and unlock files.

Paradox database (corel, Borland BDE) depending on SMB1 protocols.  The 
database uses lock files to track database table and record usage.  
Database locks are no longer being properly released after updating to 
Samba 4.18.3 from an old version (not sure which version 4.x of some sort).
