Public bug reported:

Currently we have a situation where if an instance fails to delete,
instead of having its state reverted, like we do in most places we set
it to error,deleting. This was intentionally done in
https://review.openstack.org/#/c/58829/ . We also intentionally ignore
duplicate requests to delete an instance if its already being deleted
(https://review.openstack.org/#/c/55444/). The combination of these two
things means that if an instance fails to delete for some reason a
tenant is unable to delete that instance.

It turns out this is really bad because instances in deleting state
count against quota, so the tenant slowly looses usable quota.

To fix this, allow duplicate delete calls to go through if the instance
is in error state.
