[Why] Whenever a stream or plane is added or removed from the context the pointer will change from old to new. We set lock and validation needed in these cases. But not all of these cases match update_type from dm_determine_update_type_for_commit - an example being overlay plane updates. There are warnings for a few of these cases that should be fixed. [How] We can closer align to DC (and lock_and_validation_needed) by comparing stream and plane pointers. Since the old stream/old plane state is never freed until sometime after the commit tail work finishes we are guaranteed to never get back the same block of memory when we remove and create a stream or plane state in the same commit.
