SSL: fixed incorrect usage of #if instead of #ifdef.

In 2014ed60f17f, "#if SSL_CTRL_SET_ECDH_AUTO" test was incorrectly used
instead of "#ifdef SSL_CTRL_SET_ECDH_AUTO".  There is no practical
difference, since SSL_CTRL_SET_ECDH_AUTO evaluates to a non-zero numeric
value when defined, but anyway it's better to correctly test if the value
is defined.
