BUG/MINOR: cache: fix memory leak in parse_cache_rule error path

When the filter config (fconf) allocation fails in parse_cache_rule,
the previously allocated cache_flt_conf (cconf) and its strdup'd name
string are not freed. The error path only freed cconf but not
cconf->c.name, causing a memory leak.

No backport is needed.
