[PATCH 1/2] mm: memcg: drop obsolete cache line padding in struct mem_cgroup

[Roman Gushchin <roman.gushchin@linux.dev>]

After the grouping of the cgroup v1-related fields and the
corresponding reorganization of the struct mem_cgroup, the existing
cache line padding doesn't make much sense anymore. Let's drop
it for now and put back to new places, if necessary.
