Subject: [PATCH 7/8] tools/vm/slabinfo: cosmetic globals cleanup

checkpatch.pl complains about globals being explicitly zeroed
out: "ERROR: do not initialise globals to 0 or NULL".

New globals, introduced in this patch set, have no explicit 0
initialization; clean up the old ones to make it less hairy.
