main: Fix wrong message when terminating takes a lot of time

When a daemon needs a lot of time to exit after receiving SIGTERM, the
'xxxxxx stop' command should print something like:

[WARN] about 10 seconds passed and lock .daemon.lock exists (...)...
[WARN] about 20 seconds passed and lock .daemon.lock exists (...)...
[FAIL] about 30 seconds passed and lock .daemon.lock exists (...) - giving up

instead of:

[WARN] about 10 seconds passed and lock .daemon.lock exists (...) - giving up
[WARN] about 20 seconds passed and lock .daemon.lock exists (...) - giving up
[FAIL] about 30 seconds passed and lock .daemon.lock exists (...) - giving up

This commit fixes the bug (introduced in e701e69bac1a4bed448).
