sched_ext: Use rhashtable_lookup() instead of rhashtable_lookup_fast()

The find_user_dsq() function is called from contexts that are already
under RCU read lock protection. Switch from rhashtable_lookup_fast() to
rhashtable_lookup() to avoid redundant RCU locking.

Requires: bee8a520eb84 ("rhashtable: Use rcu_dereference_all and rcu_dereference_all_check")
