openssl: Fix potential crash with ECDH on Windows

Browse Source 
Apparently, we should use OPENSSL_free() to release memory allocated by
OpenSSL.  While it generally maps to free() that's apparently not the
case on Windows, where the ECP test vectors caused `ACCESS_VIOLATION
exception` crashes (not always the same vector).

Fixes: 74e02ff5e624 ("openssl: Mainly use EVP interface for ECDH")
