netfilter: nft_set_pipapo: Don't abuse unlikely() in pipapo_refill()
I originally used unlikely() in the if (match_only) clause, which we hit on the mapping table for the last field in a set, to ensure we avoid branching to the rest of for loop body, which is executed more frequently. However, Pablo reports, this is confusing as it gives the impression that this is not a common case, and it's actually not the intended usage of unlikely(). I couldn't observe any statistical difference in matching rates on x864_64 and aarch64 without it, so just drop it.
