netfilter: nf_log regression fix
commit ca735b3aaa945626ba65a3e51145bfe4ecd9e222 'netfilter: use a linked list of loggers' introduced an array of list_head in "struct nf_logger", but forgot to initialize it in nf_log_register(). This resulted in oops when calling nf_log_unregister() at module unload time.
