Core: fixed possible use of an uninitialized variable. The call to ngx_sock_ntop() in ngx_connection_local_sockaddr() might be performed with the uninitialized "len" variable. The fix is to initialize variable to the size of corresponding socket address type. The issue was introduced in commit 05ba5bce31e0.
