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.
