[libvirt] [PATCH 05/38] qemu: domain: Add new function to set up encrypted secrets only
Some code paths can't use the unencrypted secret. Add a helper which
checks and sets up an encrypted secret only and reuse it when setting up
the secret to decrypt the TLS private key in qemuDomainSecretInfoTLSNew.
