[PATCH 2/4] refs: cleanup code around optimization

[Karthik Nayak <karthik.188@gmail.com>]

The previous commit, moved all backends to only use/support the
'optimize' function within the `ref_store` structure. With this, cleanup
all references to the 'pack_refs' field of the structure and code around
it.
