Mykyta Yatsenko 8f6802d26d Documentation/bpf: Refresh map_lru_hash_update.dot for rqspinlock ...

Reflect the rqspinlock conversion and orphan-recovery paths added in
the previous commit:

 - All LRU locks are rqspinlock_t; any acquire can fail (AA or
   timeout). A shared "rqspinlock acquire failed" terminal collapses
   to the existing -ENOMEM exit. Dashed arrows from each acquire site
   mark the failure paths.

 - The per-CPU local freelist is now lockless (free_llist).

 - Post-steal: re-acquiring loc_l->lock to insert the stolen node
   into the local pending list can fail; on failure the node is
   published to free_llist instead of being orphaned, and the call
   returns -ENOMEM.

 - Steal-loop victim lock failure is silent: skip the victim and try
   the next CPU.
