Revert "qemu-img info: show nocow info"
This reverts commit 000c4dff . The main reason for reverting this commit before the 2.2 release is that it adds a QAPI interface that we don't want to keep: The 'nocow' flag doesn't generally make sense for block nodes, but only for the raw-posix driver. It should therefore be part of ImageInfoSpecific rather than ImageInfo. The commit contains more problems, but unlike the API stability issue they wouldn't justify reverting it.
