Log an ERROR instead of halting on unknown cache_dir types

Squid-3 can run fine without any configured cache_dir. This assists with
upgrade from older Squid-2 where COSS or NULL cache types may be present.
It also assists with backward compatibility for any future cache types
which may be added in future.
