Currently, it seems like the `initrd_filesize` was uninitialized for a while.
This is particularly problematic when attempting to `zboot` with a initrd with a size coming from `label->initrd`, because it will provide you with a 0-long initrd at boot time, making the kernel fail to continue the boot.
This fixes the issue and I confirmed it enable me booting a U-Boot on QEMU x86_64 q35 with NixOS kernel and initrds.
