Matt Riedemann b53133ba50 Cleanup allocations in failed prep_resize 
During a resize/migration, the scheduler 'doubles' the
allocations on both the source and destination hosts, which
could be the same host if resizing to the same host.

If prep_resize fails, the destination node allocations were
not getting cleaned up before rescheduling to another host.
If it's a resize to the same host, the doubled allocation
from the scheduler wasn't being subtracted for the single host.

This change cleans up the allocations from the current node
when prep_resize fails. If it's not a resize to the same host,
we're on the destination node already. If it is a resize to
the same host, remove_provider_from_instance_allocation in the
SchedulerReportClient accounts for subtracting the new flavor
from the doubled allocation.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.
