-Subject: [PATCH 2/2] - Fix silly mistake: accepted active socket created
- without group lock in SSL socket. - Replace assertion with normal validation
- check of SSL socket instance in OpenSSL verification callback (verify_cb())
- to avoid crash, e.g: if somehow race condition with SSL socket destroy
- happens or OpenSSL application data index somehow gets corrupted.
