    Commit 1f7dd3e5 ("cgroup: fix handling of multi-destination migration
    from subtree_control enabling") introduced the following compiler warning:
    
    mm/memcontrol.c: In function ‘mem_cgroup_can_attach’:
    mm/memcontrol.c:4790:9: warning: ‘memcg’ may be used uninitialized in this function [-Wmaybe-uninitialized]
       mc.to = memcg;
             ^
    
    Fix this by initializing 'memcg' to NULL.
