Decrement quota usage when deleting an instance in cell0
When we fail to schedule an instance, e.g. there are no hosts
available, conductor creates the instance in the cell0 database
and deletes the build request. At this point quota usage
has been incremented in the main 'nova' database.
When the instance is deleted, the build request is already gone
so _delete_while_booting returns False and we lookup the instance
in cell0 and delete it from there, but that flow wasn't decrementing
quota usage like _delete_while_booting was.
This change adds the same quota usage decrement handling that
_delete_while_booting performs.

Title:
quota is always in-use after delete the ERROR instances
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) ocata series:
Confirmed
Bug description:
1. stop nova-compute
2. boot an instance
3. the instance is in ERROR
4. delete the instance
5. repeat 1-4 for several times(actually, I create the instance by heat, heat
will retry to create the instance 5 times by default and will delete the error
instance before every retrying)
6. I can't boot instance after nova-compute back, the reason is "Quota
exceeded for instances: Requested 1, but already used 10 of 10 instances"
7. but in fact, there is no instance return by cmd nova-list
8. I find that the quota is still in-use, see table 'quota_usages':
