Subject: [PATCH] fix the function parameter

Upstream-Status: Pending

Original openssl_diffie_hellman_create has three parameters, but
it is reassigned a function pointer which has one parameter, and
is called with one parameter, which will lead to segment fault
on PPC, Now we simply correct the number of parameters.
