Both callers of tpm2_nvpcr_extend_bytes() duplicate the same dance: on -ENETDOWN, i.e. when the NvPCR isn't anchored yet because systemd-tpm2-setup hasn't run, they acquire the anchor secret, initialize the NvPCR, and extend again. Move this into tpm2_nvpcr_extend_bytes() itself. The only caller-specific bit, whether the anchor secret shall be synced to /var, is passed in as a parameter.
