There is a bug in the bool proto_match where the comparison uses = instead of ==.

Summary:
Fix assignment (`=`) instead of comparison (`==`) in `proto_match` check
in `report_lru_miss_stats_for_vip()`. The bug caused `proto_match` to
always evaluate to `true` (since protocol values like TCP=6 are non-zero)
and silently corrupted the `lru_miss_stat_vip` BPF map entry by
overwriting its proto field.
