samba-tool: Display friendlier error message if no password is available
‘samba-tool user get-kerberos-ticket’ is supposed to display an error
message if no password is available. However, the conditions for which
the message is displayed are impossible to be met. If ‘utf16_pw’ is not
None, the message is not displayed; if ‘utf16_pw’ *is* None, ‘nt_pass’
is assigned with a samr.Password object, which is not None — and so the
message is still not displayed.
