[ Upstream commit 8e9cd85139a2149d5a7c121b05e0cdb8287311f9 ]
Mark the device as not registered anymore when scheduling the work to
remove it. Otherwise we could end up scheduling the work multiple times
in a row, including scheduling it while it is already running.
Fixes: af9fb41ed315 ("um: virtio_uml: Fix broken device handling in time-travel")
