Only define count_free() when CONFIG_SLUB_DEBUG since that's the only
context in which it is referenced.  Only define count_partial() when
CONFIG_SLUB_DEBUG or CONFIG_SYSFS since the sysfs interface still uses it
for partial slab counts.

Also only define node_nr_objs() when CONFIG_SLUB_DEBUG since that's the
only context in which it is referenced.
