sl[au]b: Process slabinfo_show in common code
With all the infrastructure in place, we can now have slabinfo_show done from slab_common.c. A cache-specific function is called to grab information about the cache itself, since that is still heavily dependent on the implementation. But with the values produced by it, all the printing and handling is done from common code.
