dm - synchronize disk info before returning

* DM now issues a disk_config(NULL) after setting up the disk info
  in order to wait for the probe to complete, otherwise callers
  may race trying to open() the disk device before it is actually
  ready.

* Fixes cryptsetup luksOpen errors which occur due to probe races,
  typically when used in a VM or qemu.
