    minor: move assert to a slightly better place

commit 240cf62056358caa53d9e83067a4fa0407974b8c

    tcp: fix accept event on closed listening PCBs
    
    If LWIP_CALLBACK_API is not defined, but TCP_LISTEN_BACKLOG is, then
    the LWIP_EVENT_ACCEPT TCP event may be triggered for closed listening
    sockets.  This case is just as disastrous for the event API as it is
    for the callback API, as there is no way for the event hook to tell
    whether the listening PCB is still around.  Add the same protection
    against this case for TCP_LISTEN_BACKLOG as was already in place for
    LWIP_CALLBACK_API.
    
    Also remove one NULL check for LWIP_CALLBACK_API that had already
    become redundant for all callers, making the TCP_EVENT_ACCEPT code
    for that callback wrapper more in line with the rest of the wrappers.
