videobalance: add condition about segment format check

This element transformed buffer timestamp for synchronizing.
But it tried to transform timestamp before the new segment comes up.
It has to transform after segment values are set.
Otherwise, gstreamer occur critical issue by segment translation logic.

Issue is reproduced mjpeg codec by running gst-validate-1.0
