[PATCH] login: fix broken login command

[Hubert Feurstein]

It was possible to login with ctrl-c or an empty password. This bug was
introduced by the recent digest changes in common/password.c (e49a47fb).
The function check_passwd returns now also negative error codes which were
not correctly handled in do_login.
