David Miller 30321c7b65 slab: Fix off by one in object max number tests. ...

If freelist_idx_t is a byte, SLAB_OBJ_MAX_NUM should be 255 not 256, and
likewise if freelist_idx_t is a short, then it should be 65535 not
65536.

This was leading to all kinds of random crashes on sparc64 where
PAGE_SIZE is 8192.  One problem shown was that if spinlock debugging was
enabled, we'd get deadlocks in copy_pte_range() or do_wp_page() with the
same cpu already holding a lock it shouldn't hold, or the lock belonging
to a completely unrelated process.

Fixes: a41adfaa23df ("slab: introduce byte sized index for the freelist of a slab")
