[ Upstream commit
76fe8713dd0a1331d84d767e8e5d3f365d959e8a ]
Given that any particular put_device() could be the final put of the
device, the fact that there are usages of cxlds->dev after
put_device(cxlds->dev) is a red flag. Drop the reference counting since
the device is pinned by being registered and will not be unregistered
without triggering the driver + workqueue to shutdown.
