    crypto: skip secret key mutex allocation

    Secret key bytes are immutable after KeyObjectData construction. AES,
    ChaCha20-Poly1305, MAC, and KDF jobs read those bytes without acquiring
    KeyObjectData::mutex(), and secret-key export and equality do the same.

    Do not allocate a shared mutex that none of these operations uses.
    Asymmetric key mutex initialization remains eager so copies continue to
    share the same lock while asymmetric acquisitions remain.
