Pablo Neira Ayuso c1592a8994 netfilter: nf_tables: deactivate anonymous set from preparation phase 
Toggle deleted anonymous sets as inactive in the next generation, so
users cannot perform any update on it. Clear the generation bitmask
in case the transaction is aborted.

The following KASAN splat shows a set element deletion for a bound
anonymous set that has been already removed in the same transaction.
