[CIFS] Do not negotiate new POSIX_PATH_OPERATIONS_CAP yet
Samba server now expects that clients which send the new POSIX_PATH_OPERATIONS_CAP send all opens with this new SMB - and expects that clients that could send the new posix open/create but don't as indicating that they really want Windows semantics on that handle (which allows Samba to support clients which want to support both types of behaviors on different handles on the same mount) We will put this capability back in the SetFSInfo negotiation with servers like Samba when the new POSIXCreate (create/open/mkdir) code is finished.
