bcache: use MAX_CACHES_PER_SET instead of magic number 8 in __bch_bucket_alloc_set
Current cache_set has MAX_CACHES_PER_SET caches most, and the macro is used for " struct cache *cache_by_alloc[MAX_CACHES_PER_SET]; " in the define of struct cache_set. Use MAX_CACHES_PER_SET instead of magic number 8 in __bch_bucket_alloc_set.
