examples/poll_http_server is wrong

[L-jasmine]

If I Send a http request.like

GET /id=1 HTTP/1.1
Host: 127.0.0.1:8000
User-Agent: curl/7.64.1
Accept: */*
Accept-Encoding: gzip

when I send

GET /id=1 HTTP/1.1
Host: 127.0.0.1:8000

and sleep some time.
then send

User-Agent: curl/7.64.1
Accept: */*
Accept-Encoding: gzip

when client sleep.
poll_http_server go there L109

Lines 106 to 111 in 11be5c7

	let req = match parsed::http::parse_http_request(&mut bs) {
	Some(req) => req,
	None => {
	break;
	}
	};

.

break will return and drop bs.
just drop

GET /id=1 HTTP/1.1
Host: 127.0.0.1:8000
