This patch adds support for set flushing, that consists of walking over the set elements if the NFTA_SET_ELEM_LIST_ELEMENTS attribute is set. This patch requires the following changes: 1) Add set->ops->deactivate_one() operation: This allows us to deactivate an element from the set element walk path, given we can skip the lookup that happens in ->deactivate(). 2) Add a new nft_trans_alloc_gfp() function since we need to allocate transactions using GFP_ATOMIC given the set walk path happens with held rcu_read_lock.
