Subject: [PATCH] mm, slab_common: use enum kmalloc_cache_type to iterate over
 kmalloc caches

References: bnc#1155780 (VM/FS functional and performance backports)
Patch-mainline: v5.5-rc1
Git-commit: 13657d0ad90c2cbcfc6fd8d48ca52432004a8f9b

The type of local variable *type* of new_kmalloc_cache() should be enum
kmalloc_cache_type instead of int, so correct it.
