Well that will just end up with two distinct EVP_PKEY structures
referencing the same 'rsa' structure with an upped reference count. If
you're going to do that then you might as well just up the reference
count of the EVP_PKEY structure.
Now I've looked at it RSA_dup() is a non trivial problem when it deals
with things like hardware keys.
