Need Replacement for Deprecated function.

[Jeremy Harris]

Another DH problem:  I have a PEM for which DH_bits() says 512.

https://www.openssl.org/docs/man3.0/man3/DH_bits.html has
EVP_PKEY_get_bits() as a see-also, but that returns 4096.

Is it more likely I've mis-loaded the file (via a BIO),
or is EVP_PKEY_get_bits() something different?  It's doc
talks about the key in the pkey, which is suspiciously
far from the DH params...
