A recent cleanup added an unconditional reference to the nf_hooks_ingress pointer,
but that fails when CONFIG_NETFILTER_INGRESS is disabled and that member is
not present in net_device:
net/netfilter/core.c: In function 'nf_set_hooks_head':
net/netfilter/core.c:96:30: error: 'struct net_device' has no member named 'nf_hooks_ingress'
This avoids the build error by simply enclosing the assignment in an #ifdef,
which may or may not be the correct fix.
Fixes: e3b37f11e6e4 ("netfilter: replace list_head with single linked list")
