BUG/MINOR: ssl: Memory leak of DH BIGNUM fields

Browse Source 
When running HAProxy with OpenSSLv3, the two BIGNUMs used to build our
own DH parameters are not freed. It was not necessary previously because
ownership of those parameters was transferred to OpenSSL through the
DH_set0_pqg call.

This patch should be backported to 2.6.
