Well in that case it may be better to move the hooks as a whole out of
the CONFIG_SLUB_DEBUG section. Do the #ifdeffering for each call from the
hooks instead.

The point of the hook functions is to separate the hooks out of the
functions so taht they do not accumulate in the main code.

The patch moves one hook back into the main code. Please keep the checks
in the hooks.
