HTTP store doesn't allow deletion of image location

[Pranali Deore]

In case of ``http`` store, if bad value is passed for ``os_hash_value`` in validation data to add-location api, task fails which is expected but it stores location of the image which is wrong, that needs to be popped out. The location doesn't get deleted because deletion of location is not
allowed for ``http`` store. Here image needs to be deleted as it is of no use.

Steps to reproduce:
1. Create Image
$ glance image-create --container-format bare --disk-format raw --name test-image-http-store

2. Check hash value of the image
$ sha256sum cirros-0.3.4-x86_64-disk.img
34987d0d5702f8813f3ff9efe90e9e39e6926ec78658763580a79face67f3394 cirros-0.3.4-x86_64-disk.img

3. Add location to the image along with invalid os_hash_value in validation data
$ glance add-location --url http://0.0.0.0:8000/cirros-0.3.4-x86_64-disk.img af411b43-0cdf-4f6b-bc55-b66504e3f205 --validation-data '{"os_hash_algo":"sha256", "os_hash_value": "34987d0d5702f8813f3ff9efe90e9e39e6926ec78658763580a79face67f3897"}'

4. Show Image
$ glance image-show af411b43-0cdf-4f6b-bc55-b66504e3f205

Image is reverted back to 'queued' as expected but location didn't popped out, see Stores : 'web'
