This also adds NF_CT_LABELS_MAX_SIZE so it can be re-used as BUILD_BUG_ON in nft_ct. At this time, nft doesn't yet support writing to the label area; when this changes the label->words handling needs to be moved out of xt_connlabel.c into nf_conntrack_labels.c. Also removes a useless run-time check: words cannot grow beyond 4 (32 bit) or 2 (64bit) since xt_connlabel enforces a maximum of 128 labels.
