If I change LogLevel in /etc/ssh/sshd_config from default INFO to
VERBOSE then I see 'Connection closed' message but also others which I
don't want.

I also tried 'LogVerbose packet.c:sshpkt_vfatal():*' and even
'LogVerbose *:sshpkt_vfatal():*' (both with 'LogLevel INFO') but
none
worked.

What version OpenSSH are you using? Are you building from source or are
you using a vendor/distribution packaging? It's possible that someone
else has modified the log level, but in the version we ship these are
all at loglevel INFO
