Use DM_MULTIPATH_DEVICE_PATH="2" to indicate that this might be a
valid path, but we aren't certain. This happens with find_multipaths
and ignore_wwids set, when the first path to a device (or a single-path
device) is encountered. In this case, multipath needs to return
with status 0 so that the udev IMPORT statement works.
