NetworkPkg: HttpDxe response/cancel issue fix

Browse Source 
Remove timeout check for http body message receive. It should be handled
in HttpBootDxe driver for http response unblocking implementation. After
timeout removed, the Wrap date should not be freed immediately. Only the
TCP CompletionToken in Wrap date is canceled or signaled, the Wrap date
could be freed.
In addition, Http cancel token is also incorrect. Tcp Cancel should be called
to cancel TCP CompletionToken in Wrap date before close it directly. Otherwise,
some exception behavior may happened.
This patch also refine the coding style for HttpDxe driver.
