multipath-tools already carries the patches to synchronize with udev; so does parted. This should fix the issues with "device is busy" messages when doing the partitioning (but it looks as though there can still be some), and on xenial I can verify that there is just one device being created.
I've tested the patches for parted / multipath-tools on trusty and things look like they work correctly (again, aside from the "device is busy" errors, but the correct device node is created anyway).
