netfilter: Clean up unnecessary #ifdef
If CONFIG_NETFILTER_INGRESS is not enabled, nf_ingress() becomes a no-op
because it solely contains an if-clause calling nf_hook_ingress_active(),
for which an empty inline stub exists in <linux/netfilter_ingress.h>.
All the symbols used in the if-clause's body are still available even if
CONFIG_NETFILTER_INGRESS is not enabled.
The additional "#ifdef CONFIG_NETFILTER_INGRESS" in nf_ingress() is thus
unnecessary, so drop it.
