tools/mm/slabinfo: fix total_objects attribute name

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.

Fixes: 205ab99dd103 ("slub: Update statistics handling for variable order slabs")
