opj_j2k_read_cod: remove check for 'No more than one COD marker per tile' (fixes #1043) 

This check was added per daed8cc919
to fix https://github.com/uclouvain/openjpeg/issues/476 , but it does not seem
to be necessary with latest master (issue476.jp2 doesn't cause memory issues),
and breaks reading legit files.
