tcp: Make tcp_listen_with_backlog_and_err return NULL if the address/port is already used
The caller of tcp_listen_with_backlog_and_err() usually check if the return
pcb is NULL before checking the err reason. I think the commit adding
tcp_listen_with_backlog_and_err() accidently change the behavior, Fix it.
Fixes: 98fc82fa7128 ("added function tcp_listen_with_backlog_and_err() to get the error reason when listening fails")
