memcg: remove check for signal_pending() during rmdir()

After bf544fdc241da8 "memcg: move charges to root cgroup if use_hierarchy=0 in mem_cgroup_move_hugetlb_parent()", no memory reclaim will occur when removing a memory cgroup. If -EINTR is returned here, cgroup will show a warning. We don't need to handle any user interruption signal. Remove this.
