No way to provide encryption password after skipping it

[kobliha]

I "had to" skip providing the disk encryption password. Let's say because of issue #1076. Now I'm browsing through the UI and I want to enter that password somewhere because I can't resize that disk before Agama knows something about it (some additional details are at https://bugzilla.suse.com/show_bug.cgi?id=1221087)

I have not found another way than rebooting the installer.
