avformat/matroskadec: Don't reset cluster position
The new code does not rely on whether the cluster's position is set or
not to infer whether a cluster needs to be closed or not (instead, this
is done in ebml_parse), so there is no need to reset the cluster's
position at all any more. It will be automatically set to the correct
value when a cluster is entered.
