nvme-auth: Avoid C=1 warning in nvme_auth_derive_tls_psk()

The following works fine with gcc and clang, but sparse warns about
label_len not being an actual constant expression:

    const size_t label_len = sizeof(label) - 1;
    ...
    static_assert(label_len <= 255);

Avoid this by giving label an explicit length and using sizeof(label)
instead of label_len.
