The efidisk never got restored correctly before, since we don't use the
generic print_drive_commandline_full for it, and as such it didn't get a
backing image attached. This not only causes the efidisk data to be lost
on restore, but also an error at the end, since we try to remove a
non-existing PBS blockdev.
Since it is attached differently to a regular drive, adding PBS backing
would be more difficult, but not to worry: an efidisk is small enough
that it doesn't hurt performance to just restore it via the regular
mechanism before starting the VM, and simply excluding it from the live
restore entirely.

I guess in QEMU < 6.0 this didn't cause an error, since I definitely tested with
EFI VMs before, however, it would have never actually restored the data and
instead always created a new one.
