test-qht: perform lookups under rcu_read_lock
qht_lookup is meant to be called from an RCU read-critical section. Make sure we're in such a section in test-qht when performing lookups, despite the fact that no races in qht can be triggered by test-qht since it is single-threaded. Note that rcu_register_thread is already called by the rcu_after_fork hook, and therefore duplicating it here would be a bug. Signed-off-by: Emilio G.
