bug fix. huge memory usages for matroska file with errors

[Cause]
  According to the current specifications for matroska,
  it needs to be parsed to the end of the file when tag has no length.
  If a normal tag does not appear immediately, unnecessary memory
  for embl list is used to read the the end of the file.
[Solution]
  To avoid huge memory usages, return error for unknown-length tags.
