Initialize console if -U is specified

In absence of console or when console reference line is set
to nil, noPwd is set to true which disables password prompt
and when console is not initialized, password cannot be read
from user. This is why when -i is specified, console is not
initialized and we do not see password prompt.
This commit initializes console even if -U is specified so
that password can be read interactively from user.
