Bug 8229: fix bad git merge of handleFloatingIpPortUpdated

Cherry-pick [1] was cherry-picked without any conflicts,
but git merge seems to have created an error -
the trailing code lines of NeutronPortChangeListener.update() were
incorrectly moved to handleFloatingIpPortUpdated().

This causes an uncaught exception, and possibly breaks the QoS update code
that was excluded from the update() function because of that.
