Astobj2: Ensure all calls to __adjust_lock pass a valid object.

Browse Source 
__adjust_lock doesn't check for invalid objects, and doesn't have an
appropriate return value for invalid objects.  Most callers of
__adjust_lock pass objects that have already been confirmed valid,
this change adds checks before the remaining calls.
