avformat/matroskadec: Remove redundant initialization 

Every new element of an EbmlList is zeroed initially in
ebml_parse_elem, so that in particular a SimpleBlock's duration is
initialized to zero. Therefore it is unnecessary to initialize this
field again (for SimpleBlocks) in matroska_parse_cluster_incremental.
