mm/slub: make add_full() condition more explicit

Browse source

The commit below is incomplete, as it didn't handle the add_full() part.
commit a4d3f8916c ("slub: remove useless kmem_cache_debug() before
remove_full()")

This patch checks for SLAB_STORE_USER instead of kmem_cache_debug(), since
that should be the only context in which we need the list_lock for
add_full().
