netfilter: nf_tables: add NFT_TRANS_PREPARE_ERROR to deal with bound set/chain
[ Upstream commit 26b5a5712eb85e253724e56a54c17f8519bd8e4e ]
Add a new state to deal with rule expressions deactivation from the
newrule error path, otherwise the anonymous set remains in the list in
inactive state for the next generation. Mark the set/chain transaction
as unbound so the abort path releases this object, set it as inactive in
the next generation so it is not reachable anymore from this transaction
and reference counter is dropped.
