tcp: Prevents a 0 sized (invalid) backlog

Browse Source 
commit 44e1a2d8e2 accidently includes below changes in tcp_listen_with_backlog
 -  tcp_backlog_set(lpcb, backlog);
 +  lpcb->backlog = backlog;

Thus pass 0 to the backlog parameter of netconn_listen_with_backlog() fails.

Fixes: 44e1a2d8e2 ("define tcp_backlog_set() as dummy-define when backlog feature is disable")
