netfilter: nft_fib: allow from forward/input without iif selector
[ Upstream commit e8ded22ef0f4831279c363c264cd41cd9d59ca9e ]
This removes the restriction of needing iif selector in the
forward/input hooks for fib lookups when requested result is
oif/oifname.
Removing this restriction allows "loose" lookups from the forward hooks.
