Commit 459f5ffa24 ("OvmfPkg/QemuKernelLoaderFsDxe: rework direct
kernel boot filesystem") has a small change in behavior: In case
there is no data the file is not created and attempts to open file
return EFI_NOT_FOUND. Old behavior was to add a zero-length file
to the filesystem.
Fix GenericQemuLoadImageLib to handle EFI_NOT_FOUND correctly for
'initrd' and 'cmdline'.
