Prevent an assertion failure when using WebSockets (me-no-dev#584)

matt123p · me-no-dev · commit 5ea49e313d7d · 2019-09-21T13:27:34.000+03:00
Frequently when using Web Sockets you will get the assert failure:
    	assertion "new_rcv_ann_wnd &lt;= 0xffff" failed: file "/Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/lwip/lwip/src/core/tcp.c", line 779, function: tcp_update_rcv_ann_wnd

This will happen particulary when you close the browser window.  This change
prevents the issue from occuring.
