mbcache: Remove unused features
The mbcache code was written to support a variable number of indexes,
but all the existing users use exactly one index. Simplify to code to
support only that case.
There are also no users of the cache entry free operation, and none of
the users keep extra data in cache entries. Remove those features as
well.
