[Samba] Win7 clients problem after upgrading samba file server to 4.12 on Arch

[pavlos]

@Rowland,
Installing and changing to LTS kernel 5.4.38-1-lts doesn't help.
Downgrading samba and smbclient to 4.11.3 DOES help.

@Andrew, let me first clean up with kernel/samba versions, set log level to
10 and log limit to 0, delete all logs and repeat the whole exercise.
Please advice how to get a network capture, I am not that expert...

Regards, Pawel.
