From: Martin Wilck <mwilck@xxxxxxxx>
device-mapper sets the flag DM_UDEV_DISABLE_OTHER_RULES_FLAG to 1 for
devices which are unusable. They may be no set up yet, suspended, or
otherwise unusable (e.g. multipath maps without usable path). This
flag does not necessarily imply SYSTEMD_READY=0 and must therefore
be tested separately.

Changes in v2:
- Moved the check further up; DM_UDEV_DISABLE_OTHER_RULES_FLAG must
be checked before ID_FS_TYPE to be effective
