BUG/MINOR: ssl: correctly initialize ssl ctx for invalid certificates
Bug reported by John Leach: no-sslv3 does not work using some certificates.
It appears that ssl ctx is not updated with configured options if the
CommonName of the certificate's subject is not found.
It applies only on the first cerificate of a configured bind line.
There is no security impact, because only invalid nameless certficates
are concerned.
This fix must be backported to 1.5
