internal/download: don't discard dst.Close error#34866

When `io.Copy` succeeds but the buffered `Close` fails (e.g. disk full on `Flush`), the error was swallowed and verification reported a misleading hash mismatch instead of the real I/O failure. Keep the `Close` error when `io.Copy` didn't already produce one.
