naughty: Fix the `ignore_suspend` property.

By fixing some suspend bugs a few weeks ago, I "regressed" this
a little. By that, I mean there were bugs in the suspend code
which caused `ignore_suspend` to work simply because suspend
globally failed rather than `ignore_suspend` being implemented
correctly.

Fix #3465
