udev: import previous results of blkid when in suspended state
Follow-up for e10f67e917.

The commit e10f67e917 tries to keep device
node symlinks even if the device is in the suspended state. However,
necessary properties that may previously obtained by the blkid command
were not imported at least in the .rules file. So, unless ID_FS_xyz
properties are imported by another earlier .rules file, the device node
symlinks are still lost when event is processed in the suspended state.

Let's explicitly import the necessary properties.

# Add inotify watch to track changes on this device.
# Using the watch rule is not optimal - it generates a lot of spurious
# and useless events whenever the device opened for read-write is closed.
# The best would be to generete the event directly in the tool changing
# relevant information so only relevant events will be processed
# (like creating a filesystem, changing filesystem label etc.).

# But let's use this until we have something better...
