sysctl: Fix unused function warning
The newly added bpf_stats_handler function has the wrong #ifdef
check around it, leading to an unused-function warning when
CONFIG_SYSCTL is disabled:
kernel/sysctl.c:205:12: error: unused function 'bpf_stats_handler' [-Werror,-Wunused-function]
static int bpf_stats_handler(struct ctl_table *table, int write,
Fix the check to match the reference.
Fixes: d46edd671a14 ("bpf: Sharing bpf runtime stats with BPF_ENABLE_STATS")
