slub: Disable NUMA remote node defragmentation by default
Switch remote node defragmentation off by default. The current settings can
cause excessive node local allocations with hackbench:
SLAB:
% cat /proc/meminfo
MemTotal: 7701760 kB
MemFree: 5940096 kB
Slab: 123840 kB
SLUB:
% cat /proc/meminfo
MemTotal: 7701376 kB
MemFree: 4740928 kB
Slab: 1591680 kB
[Note: this feature is not related to slab defragmentation.]
