mm: memcg: gather memcg1-specific fields initialization in memcg1_memcg_init()

Gather all memcg1-specific struct mem_cgroup's members initialization in a
new memcg1_memcg_init() function, defined in mm/memcontrol-v1.c. 
Obviously, if CONFIG_MEMCG_V1 is not set, there is no need to initialize
these fields, so the function becomes trivial.
