Dmitry Osipenko ffbb9de588 util/mesa-db: Fix crash on compacting empty DB
Fix mesa_db_compact() segfaulting if compacted DB is empty. This crash
happens on writing cache entry that is bigger than DB's size limit and
when DB is empty, which can be triggered by setting DB size to a small
value.

Fixes: 32211788d0 ("util/disk_cache: Add new mesa-db cache type")
