    udp: provide udp{4,6}_lib_lookup for nf_socket_ipv{4,6} · 30f58158

    Since commit ca065d0c ("udp: no longer use SLAB_DESTROY_BY_RCU")
    the udp6_lib_lookup and udp4_lib_lookup functions are only
    provided when it is actually possible to call them.
    
    However, moving the callers now caused a link error:
    
    net/built-in.o: In function `nf_sk_lookup_slow_v6':
    (.text+0x131a39): undefined reference to `udp6_lib_lookup'
    net/ipv4/netfilter/nf_socket_ipv4.o: In function `nf_sk_lookup_slow_v4':
    nf_socket_ipv4.c:(.text.nf_sk_lookup_slow_v4+0x114): undefined reference to `udp4_lib_lookup'
    
    This extends the #ifdef so we also provide the functions when
    CONFIG_NF_SOCKET_IPV4 or CONFIG_NF_SOCKET_IPV6, respectively
    are set.
    
    Fixes: 8db4c5be ("netfilter: move socket lookup infrastructure to nf_socket_ipv{4,6}.c")
