[pve-devel] [PATCH manager] ui: PBSEdit: cleanup iframe for paperkey

[Aaron Lauterer <a.lauterer@proxmox.com>]

Otherwise the iframe used to print the paperkey will remain even after
the encryption key window is closed.
Additionally clean before creating a new one as otherwise we might end
up with multiple iframes.
