With the disappearance of nft_meta_init_validate_get(), I will need to add
an #ifdef/#endif clause for bridge key support. Or I would copy and adapt
this new nft_meta_get_init() in nft_meta_bridge.c.
Don't you think nft_meta_validate_get() could be kept?

Rest is fine and indeed it simplifies things on my side (no need to c/p
the old nft_meta_init,
here I can reuse existing nft_meta_set_init)
