netfilter: nft_set_pipapo: make pipapo_clone helper return NULL
Currently it returns an error pointer, but the only possible failure
is ENOMEM.
After a followup patch, we'd need to discard the errno code, i.e.
x = pipapo_clone()
if (IS_ERR(x))
return NULL
or make more changes to fix up callers to expect IS_ERR() code
from set->ops->deactivate().
So simplify this and make it return ptr-or-null.
