Subject: [PATCH 2/2] Skip persistent device link creation on multipath device
 paths

When a device is marked as a multipath device path by setting
DM_MULTIPATH_DEVICE_PATH="1" udev should not create any
persistent symlinks to that device.
Otherwise systemd will get confused about which device to use.
