As pointed out in the previous patch, I think we should keep this
API but convert it to a macro for inlining. rhashtable_lookup() would
then just be a user of this macro.

It might even be worth to hardcode rhashtable_lookup() to jhash
and require users which require a different hash function to
use rhashtable_lookup_compare().
