[PATCH 1/2] efi_loader: Avoid using efi_update_capsule() from update capsule on disk

[Masami Hiramatsu <masami.hiramatsu@linaro.org>]

The efi_update_capsule() may have to handle the capsule flags as an UEFI
runtime and boottime service, but the capsule-on-disk process doesn't.
Thus, the capsule-on-disk should use the efi_capsule_update_firmware()
directly instead of efi_update_capsule(). To keep the consistency
ESRT also will be updated after all capsule updates are completed.
