netfilter: nft_hash: support deletion of inactive elements
New elements are inactive in the preparation phase, and its
NFT_SET_ELEM_BUSY_MASK flag is set on.
This busy flag doesn't allow us to delete it from the same transaction,
following a sequence like:
begin transaction
add element X
delete element X
end transaction
This sequence is valid and may be triggered by robots. To resolve this
problem, allow deactivating elements that are active in the current
generation (ie. those that has been just added in this batch).
