Subject: [PATCH] core/device: device_coldplug(): don't set DEVICE_DEAD

dm-crypt device units generated by systemd-cryptsetup-generator
habe BindsTo= dependencies on their backend devices. The dm-crypt
devices have the db_persist flag set, and thus survive the udev db
cleanup while switching root. But backend devices usually don't survive.
These devices are neither mounted nor used for swap, thus they will
seen as DEVICE_NOT_FOUND after switching root.

The BindsTo dependency will cause systemd to schedule a stop
job for the dm-crypt device, breaking boot:

[   68.929457] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Unit is stopped because bound to inactive unit dev-disk-by\x2duuid-3bf91f73\x2d1ee8\x2d4cfc\x2d9048\x2d93ba349b786d.device.
[   68.945660] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Trying to enqueue job systemd-cryptsetup@cr_root.service/stop/replace
[   69.473459] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Installed new job systemd-cryptsetup@cr_root.service/stop as 343

Avoid this by not setting the state of the backend devices to
DEVICE_DEAD.

Fixes the LUKS setup issue reported in #23429.
