The newly added nft_ct_get_eval_counter() function is only used when
CONFIG_NF_CONNTRACK_LABELS is set, otherwise gcc warns about the
unused definition:
netfilter/nft_ct.c:34:12: warning: 'nft_ct_get_eval_counter' defined but not used [-Wunused-function]
static u64 nft_ct_get_eval_counter(const struct nf_conn_counter *c,
This marks the function __maybe_unused to shut up the warning.
