[PATCH 7/7] Don't require latency_warn_ms from bcache_util.o

When building as a module, we can't see this variable. This removes
useful debugging; probably some restructuring would be better here.

I'm not clear on the responsibilities of bcache.c, vs. bcache_util.c,
there seem to be references in both directions.
