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.
