We don't send a complete data URL to NetworkProcess, with the idea that it can do scheduling, and tell WebProcess to perform the actual load. But there is no longer any way to tell WebProcess to load, so I'm going to just remove this code for now. We can look at optimizations later. <rdar://problem/12857080>
