Bug 871438 - Reset value when file transfer session starts. r=gyeh, a=leo+

When the transferring session was stopped, mBodySegmentLength wouldn't reset

next transferring doesn't contain header Body or EndOfBody, which would invoke
ExtractPacketHeaders() and refresh mBodySegmentLength in the function.
