tools/mm/slabinfo: fix total_objects attribute name

Browse Source 
SLUB exports the total_objects sysfs attribute, but slabinfo tries to read
objects_total. As a result, the lookup fails and the field remains zero.

Use the correct attribute name and rename the corresponding structure
member to match.
