[pve-devel] [PATCH qemu-server 3/3] live-restore: ignore missing efidisk

Don't attempt to restore a configured efidisk for SeaBIOS VMs when it is
missing. This can happen, as configured efidisks do not get backed up if
the BIOS setting is not OVMF.

Note that in case of OVMF VMs a missing efidisk is still treated as an
error, as that indicates a broken backup in general.
