Subject: mm/slub.c: remove a redundant assignment in ___slab_alloc()

When the code comes to this point, there are two cases:
1. cpu_slab is deactivated
2. cpu_slab is empty

In both cased, cpu_slab->freelist is NULL at this moment.

This patch removes the redundant assignment of cpu_slab->freelist.
