Subject: [PATCH] Update sockets.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1、更正lwip_accept()中调用netconn_peer()失败时，netconn_delete()会被调用两次，从而导致进入rt_assert_handler()错误。
原因：(https://savannah.nongnu.org/bugs/?55536) bug #55536: lwIP 2.1.2: netconn_delete() called twice from lwip_accept()
