[PATCH v3 6.6.y 8/8] netfilter: nft_set_pipapo: remove dirty flag

[Natarajan KV <natarajankv91@gmail.com>]

Adaptation of commit 532aec7e878b ("netfilter: nft_set_pipapo: remove
dirty flag") to 6.6.122.

After the previous change, when a clone exists, the dirty flag
is always true, when clone is NULL, dirty is always false.
Remove it.
