bcache: replace hard coded number with BUCKET_GC_GEN_MAX
In extents.c:bch_extent_bad(), number 96 is used as parameter to call btree_bug_on(). The purpose is to check whether stale gen value exceeds BUCKET_GC_GEN_MAX, so it is better to use macro BUCKET_GC_GEN_MAX to make the code more understandable.
