seqerror: check error from iter.Seq2 range is not discarded

When ranging over an iter.Seq2[T, error], the error must be checked (typically via an if err != nil block with a scope-exiting statement) or propagated (passed to a yield function or other call). Discarding the error with a blank identifier or omitting it entirely is reported unless suppressed with a //seq:err-checked comment.
