Thank you for your bug report. However, this is intentional as a workaround for bug 445852, and is explained in the changelog for the last devicekit-disks upload (which should have been viewable in update-manager when you updated):
* Add 11-disable-smart-probing.patch: Disable ATA SMART probing on ATA
disks. It causes hardware damage to a lot of SSD disks. This is a
workaround, until a real fix in libatasmart is found. (LP: #445852)
