functional: Wait for revert resize to complete
When reverting a resize, we need to wait for the migration status to
change to 'reverted', but we also need to wait for the relevant
versioned notification to be emitted. The reason for this is noted in a
couple of places, including the '_revert_resize' helper in the
'nova.tests.functional.integrated_helpers.InstanceHelperMixin' module:
[T]he migration status is changed to "reverted" in the dest host
revert_resize method but the allocations are cleaned up in the source
host finish_revert_resize method so we need to wait for the
finish_revert_resize method to complete.
Two tests in the 'test_cross_cell_migrate' test module were not doing
this wait, resulting in intermittent failures in CI due to the races.
Resolve this now.
