[PATCH 01/15] read-cache: fix memleak

`ce` is allocated in make_cache_entry and should be freed if it is not
used any more. refresh_cache_entry as a wrapper around refresh_cache_ent
will either return `ce` or a new updated cache entry which is allocated
to new memory. In that case we need to free `ce` ourselfs.
