What changes were proposed in this pull request?
Currently on demand scanning does a full check (data and metadata) of closed containers only. Data scan of blocks can only be done on closed containers, but metadata scan can be done on open containers. When an open container is queued for on-demand scanning, the scanner should do a metadata scan instead of ignoring it.
This PR introduces metadata scan for open containers as well.
