rhashtable: fix false-positive lockdep splat on rhltable destruction

Browse Source 
Blamed commit removed ht->mutex usage during destruction but forgot to
switch rhashtable_free_one() to rcu_dereference_raw(), this triggers a
lockdep splat when an rhltable gets zapped.

Fixes: 09ae540e1d ("rhashtable: drop ht->mutex in rhashtable_free_and_destroy()")
