    Fix missing RP generation update
    
    Most of the methods that increase the generation for a resource provider
    also update the value of generation in the object that calls it, but
    there was one place where it was missing. This patch fixes that
    omission.

Title:
  Resource Provider generation update missing

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Most of the methods that increase the generation for a resource
  provider also update the value of `generation` in the object that
  calls it, but there is one place where it was missing: the
  _set_allocations() method of the AllocationList class. This resulted
  in some ResourceProvider references having stale values for
  `generation`, which would cause a ConcurrentUpdateDetected exception
  to be raised.
