netfilter: nft_set_pipapo: Store real pointer, adjust later.

The struct nft_pipapo_scratch is allocated, then aligned to the required
alignment and difference (in bytes) is then saved in align_off. The
aligned pointer is used later.
While this works, it gets complicated with all the extra checks if
all member before map are larger than the required alignment.

Instead of saving the aligned pointer, just save the returned pointer
and align the map pointer in nft_pipapo_lookup() before using it. The
alignment later on shouldn't be that expensive. With this change, the
align_off can be removed and the pointer can be passed to kfree() as is.
