Replace slub with slab from perf comparison.

SLUB is said to be next generation of SLAB and replacement
for SLAB. But At least in windcharger board, I see serious
page fragmentation: even though similar free memory with SLAB,
but most are 1,2,4 pages region. This results in big page alloc
failures. SLAB is much better.
