ovpnmain.cgi: Fixes bug#13548 - imported N2N client connections get disabled instead of no-pass

- When bug#11408 was fixed it was missed that key 41 has disabled inserted into it when
   uploading into the N2N client. This replaced the no-pass entry for all N2N connections
   resulting in the ovpnmain.cgi not being able to show the status correctly as the code
   looks for pass or no-pass.
- The disabled entry has been present for a very long time and is not utilised anywhere
   in the code.
- This fix ensures that key 41 in the uploaded N2N connection has no-pass entered
- Tested out and confirmed in my vm testbed.
