mod_admin_telnet: Handle unavailable cipher info (fixes #1510) The LuaSec :info() method gathers info using the OpenSSL function SSL_get_current_cipher(). Documentation for this function states that it may return NULL if no session has been established (yet). If so, the LuaSec functions wrapping this return nil, triggering a nil-indexing error in mod_admin_telnet.
