* Solves #9362
Fix double-free crash in BSecureSocket when cert. verification fails

* BSecureSocket::CertificateVerificationFailed() took a BCertificate
  instance by value as parameter.
  BCertificate deletes internal data in its destructor. Passing an
  object by value creates a copy, so the copy attempted to delete
  the internal data again during its destruction.
  This caused mail_daemon to crash here when it came across a failed
  certificate.

* Fix: pass BCertificate object as reference.
