netfilter: bpf: Only define get_proto_defrag_hook() if necessary
Before, we were getting this warning:
net/netfilter/nf_bpf_link.c:32:1: warning: 'get_proto_defrag_hook' defined but not used [-Wunused-function]
Guard the definition with CONFIG_NF_DEFRAG_IPV[4|6].
Fixes: 91721c2d02d3 ("netfilter: bpf: Support BPF_F_NETFILTER_IP_DEFRAG in netfilter link")
