Closed requested to merge haraldh/cryptsetup:finished into master
A finished hook prevents dracut-initqueue from exiting and lets it finish the batched jobs. Without a "finished hook" and without "root=" on the kernel command line, the reencrypt job would not be executed.
Normally you want to reencrypt without a "root=" on the kernel command and want to reboot after the reencrypt job is done.
This patch adds the missing "finished hook".
