mm: memcontrol: rename mem_cgroup_from_slab_obj()
In addition to slab objects, this function is used for resolving non-slab
kernel pointers. This has caused confusion in recent refactoring work.
Rename it to mem_cgroup_from_virt(), sticking with terminology established
by the virt_to_<foo>() converters.
