BUG/MINOR: ssl: fix warning about ssl-min/max-ver support

In 84e417d8 ("MINOR: ssl: support Openssl 1.1.1 early callback for
switchctx") the code was extended to also support OpenSSL 1.1.1
(code already supported BoringSSL). A configuration check warning
was updated but with the wrong logic, the #ifdef needs a && instead
of an ||.

Reported in #54.

Should be backported to 1.8.
