[PATCH 13/15] bcache: use MAX_CACHES_PER_SET instead of magic number 8 in __bch_bucket_alloc_set

[Coly Li]

From: Shenghui Wang <shh...@foxmail.com>

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.
