Pablo Neira Ayuso a26c1e49c8 netfilter: nf_tables: do not update stateful expressions if lookup is inverted 
Initialize set lookup matching element to NULL. Otherwise, the
NFT_LOOKUP_F_INV flag reverses the matching logic and it leads to
deference an uninitialized pointer to the matching element. Make sure
element data area and stateful expression are accessed if there is a
matching set element.

This patch undoes 24791b9aa1 ("netfilter: nft_set_bitmap: initialize set
element extension in lookups") which is not required anymore.

Fixes: 339706bc21 ("netfilter: nft_lookup: update element stateful expression")
