netfilter: nf_tables_offload: incorrect flow offload action array size
commit b1a5983f upstream. immediate verdict expression needs to allocate one slot in the flow offload action array, however, immediate data expression does not need to do so. fwd and dup expression need to allocate one slot, this is missing. Add a new offload_action interface to report if this expression needs to allocate one slot in the flow offload action array.
