souphttpsrc: make flow return values handling clearer
The flow return values was stored in the element before because the result had to be set from callbacks. This is not the case anymore, we can return the flow result directly from functions, making the code easier to understand. https://bugzilla.gnome.org/show_bug.cgi?id=777222
