efi_loader: bootbin: do not load an initrd if none is provided
Do not try to create an initrd device path nor try to register
an initrd with the EFI_LOAD_FILE2_PROTOCOL if none is provided.
Handle initrd installation in efi_binary_run_dp with
efi_install_initrd, imitating what is done for the fdt.
Fixes: 36835a9105c ("efi_loader: binary_run: register an initrd")
