Public bug reported:
VM resize and confirm on the same host fails with custom resources, as the old
resources are not deallocated after 'confirmResize'.
Steps to reproduce:
- boot a VM with old_flavor
- resize to new_flavor to the same host
- send confirmResize
- check usages and compare with new_flavor, and there will be double
allocations (old_flavor + new_flavor)
