[Samba] "samba-tool -V" output: samba-tool: missing subcommand

[Franta Hanzlik]

It seems as samba-tool bug or problem with my Samba build.
When run commands:

samba-tool -V

output (all on stdout) is:
samba-tool: missing subcommand

4.20.4
#----------------
Similar output is with '-h' option. IMO at least in the first case,
the message about the missing subcommand should not be printed.
Or to stderr and not to stdout.
