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
"smart", when the first path to a device (or a single-path
device) is encountered, and the device is neither blacklisted,
nor marked failed, nor whitelisted in the wwids file.
