netfilter: nfnetlink: remove static declaration from err_list
Otherwise, different subsys will race to access the err_list, with holding the different nfnl_lock(subsys_id). But this will not happen now, since ->call_batch is only implemented by nftables, so the err_list is protected by nfnl_lock(NFNL_SUBSYS_NFTABLES).
