There is a race where the BO refcount might drop to 0 before the dmabuf/name import paths had a chance to grab a reference for a BO found in the handle_table. The easiest solution is to keep the refcount stable as long as the table_lock is held. While a more involved scheme of rechecking the refcount before actually destroying the BO might also work, the bo_del path isn't called very often, so micro-optimizing a single mutex_lock seems to be over-engineered, so go for the easy solution.
