Subject: [PATCH] Bug 1416084. P2 - wake up readers when download is suspended.
 r=bechen,gerald

It is possible that download is suspended after all bytes are received but
before OnStopRequest is notified. In that case, we will fail to wake up the
readers waiting to read the partial block and cause bug 1412737 comment 30.
