[netwerk] Make nsIncrementalStreamLoader's GetNumBytesRead threadsafe.
This prevents a potential race and simplifies the code a bit by keeping the
bytes read separate instead of using mData, which is modified from another
thread from OnDataAvailable.
Relaxed atomics are fine for these, since they don't guard any memory.
