Title:
  Incorrect Resource Tracker usage calculation for resize

Status in OpenStack Compute (Nova):
  Opinion

Bug description:
  When an instance errors out during resize and the task state remains
  in either 'resize_migrated' or 'resize_finish', resource_tracker
  doesn't consider the instance while calculating the resource because
  the instance host and node are set to destination and the migrations
  are not considered because the instance is in 'error' state.

  The instance resize cannot be reverted if the source node is filled up
  before the revert.
