partitioning: pass along reference to parent when uninitializing.

* Fixes problems with setting the partition name after uninitializing
  a partition in DriveSetup. Previously, UninitializeJob() was
  followed by SetStringJob(), but the kernel was updating the
  change counter for the parent partition when uninitializing a
  partition, leading to SetStringJob() having an incorrect change
  counter for the parent partition. Now the parent change counter
  will be correct when SetStringJob() runs.
