When the code enters the retry logic, the number of retries = servers_list count * max_redirection * max_connection_attempts. When calculating the servers list in the try_hosts_slots method, the server list corresponding to each solt is actually stored, which will cause the same server to appear multiple times in the list, and the number of retries will become slots count * max_redirection * max_connection_attempts. This commit fixes this issue.
