udev: create symlinks and watch even in suspended state
If a dm device is suspended, we can't run blkid on it. But earlier
rules (e.g. 11-dm-parts.rules) might have imported previously scanned
properties from the udev db, in particular if the device had been correctly
set up beforehand (DM_UDEV_PRIMARY_SOURCE_FLAG==1). Symlinks for existing
ID_FS_xyz properties must be preserved in this case. Otherwise lower-priority
devices (such as multipath components) might take over the symlink
temporarily.
Likewise, we should't stop watching a temporarily suspended, but previously
correctly configured dm device.
