Bugzilla: 579692
Upstream commit: 37905d6ae53d8a9f0744867a8cf2dad6e7ae3674

The boot once options seems to have gotten broken since it originally
went in.  We need to wait until the second time restore_boot_devices()
gets called before restoring the standard boot order and removing itself
from the reset list.
