[PATCH] mm/slub: fix help comment of SLUB_DEBUG[_ON]

Since commit 081248de0a02 ("kset: move /sys/slab to /sys/kernel/slab"),
the SYSFS path of slab was modified, so fix up the help comment of
SLUB_DEBUG to use the correct one.

And now the "slub_debug" parameter on boot that is support for more
fine grained debug control, so fix up help comment of SLUB_DEBUG_ON
for "no support" to "support".
