net-memcg: Pass struct sock to mem_cgroup_sk_under_memory_pressure().
We will store a flag in the lowest bit of sk->sk_memcg.
Then, we cannot pass the raw pointer to mem_cgroup_under_socket_pressure().
Let's pass struct sock to it and rename the function to match other
functions starting with mem_cgroup_sk_.
Note that the helper is moved to sock.h to use mem_cgroup_from_sk().
