A geneve tunnel object with an empty options array ("tunnel": []) leaves obj->tunnel.geneve_opts uninitialized; obj_tunnel_add_opts() then walks the uninitialized list head and nft -j crashes (SEGV in nftnl_tunnel_opt_geneve_set via near-NULL deref).

Applied.  I moved the crasher to testcases/bogons.
