slub: disallow changing cpu_partial from userspace for debug caches
For caches with debugging enabled, "slub: Switch per cpu partial page support off for debugging" changes cpu_partial to 0. It shouldn't be tunable from userspace for such caches, otherwise the same accounting issues arise during validation. This patch disallows tuning /sys/kernel/slab/cache/cpu_partial to be non- zero for caches with debugging enabled.
