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.
