netfilter: nft_{fwd,dup}_netdev: add offload support
This patch adds support for packet mirroring and redirection. The
nft_fwd_dup_netdev_offload() function configures the flow_action object
for the fwd and the dup actions.
Extend nft_flow_rule_destroy() to release the net_device object when the
flow_rule object is released, since nft_fwd_dup_netdev_offload() bumps
the net_device reference counter.
