memcg: remove pointless next_mz nullification in mem_cgroup_soft_limit_reclaim()
next_mz is assigned to NULL if __mem_cgroup_largest_soft_limit_node
selects the same mz. This doesn't make much sense as we assign to the
variable right in the next loop.
Compiler will probably optimize this out but it is little bit confusing
for the code reading.
