      Description

      vio_end() is called twice in this fragment in libmysql/libmysql.c in case of embedded server:

      void STDCALL mysql_server_end()
      {
        if (!mysql_client_init)
          return;
       
        mysql_client_plugin_deinit();
       
      #ifdef EMBEDDED_LIBRARY
        end_embedded_server();
      #endif
        finish_client_errs();
        vio_end();

      First time it's called from end_embedded_server() via clean_up().
      Second time it's called from mysql_server_end() directly.

      The problem does not show up in any ways with the standard
      yassl and openssl libraries, but it's reported that mysqltest_embedded
      hangs when linked against a custom built openssl library.
      See the comments in the end of MDEV-4890.
