Subject: [PATCH] tty-ask-password-agent: return negative errno

Return negative errno in wall_tty_block(). get_ctty_devnr() already
returns a negative errno in case of failure, no need to negate it again.

Reported-by: Simon <hwold@odai.homelinux.net>

(cherry-picked from ee0e4cca5ac37a094dfe1074907dae70c7b7701c)

Resolves: #1147524
