netfilter: bridge: fix CONFIG_NF_DEFRAG_IPV4/6 related warnings/errors
br_nf_ip_fragment() is not needed when neither CONFIG_NF_DEFRAG_IPV4 nor
CONFIG_NF_DEFRAG_IPV6 is set.
struct brnf_frag_data must be available if either CONFIG_NF_DEFRAG_IPV4
or CONFIG_NF_DEFRAG_IPV6 is set.
Fixes: efb6de9b4ba0 ("netfilter: bridge: forward IPv6 fragmented packets")
