mm, slub: use kmem_cache_debug_flags() in deactivate_slab()

Commit 9cf7a1118365 ("mm/slub: make add_full() condition more explicit")
replaced an unnecessarily generic kmem_cache_debug(s) check with an
explicit check of SLAB_STORE_USER and #ifdef CONFIG_SLUB_DEBUG.

We can achieve the same specific check with the recently added
kmem_cache_debug_flags() which removes the #ifdef and restores the
no-branch-overhead benefit of static key check when slub debugging is not
enabled.
