Previously, we were calling del_qgroup_item, and ignoring the return code resulting in a potential to have divergent in-memory state without an error. Perhaps, it makes sense to handle this error code, and put the filesystem into a read only, or similar state.
This patch only adds reporting of the error if the error is fatal, (any error other than qgroup not found).
