...G...PS. [ZBX-10820] refactored zbx_tcp_check_security() (continued)
 
- renamed zbx_tcp_check_security() to zbx_tcp_check_allowed_peers() to better reflects its purpose
  (based on ZBX-11592 comments),
- deleted 'action_if_empty' argument - if allowed peer list is empty, there is no need to call the function,
- fixed typo in comment.
