memcg: do not use vmalloc for mem_cgroup allocations
The vmalloc was introduced by 33327948782b ("memcgroup: use vmalloc for mem_cgroup allocation"), because at that time MAX_NUMNODES was used for defining the per-node array in the mem_cgroup structure so that the structure could be huge even if the system had the only NUMA node. The situation was significantly improved by commit 45cf7ebd5a03 ("memcg: reduce the size of struct memcg 244-fold"), which made the size of the mem_cgroup structure calculated dynamically depending on the real number of NUMA nodes installed on the system (nr_node_ids), so now there is no point in using vmalloc here: the structure is allocated rarely and on most systems its size is about 1K.
