The subregion is changing its state to issued, only in ufshpb_issue_map_req.
Although you already know that those physical addresses are no longer valid in
ufshpb_update_active_info.
Can we mark that this subregion is no longer valid earlier, so not to keep
sending faulty HPB-READ to that subregion?
Thanks,
