Don't set RTT property if original connection null

When mOriginalConnection is null, don't set the RTT property even if we
get an onRttInitiated. Since mOriginalConnection is used to compute the
RTT property, this'll always set the RTT property to false. The property
will be set once mOriginalConnection gets set.
