Chunk server: fix client state machine missing connection read enable by moving all the relevant logic at the end at the event handler, and set connection read at recursion 1 to 0 if client is waiting for io buffers, or to default (max request header size) if the read isn't enabled, otherwise do not change it to preserve write request handler setting to get the rest of the request body.
