net: Dereference pointer-value of sk_prot->memory_pressure
2e685cad57 (tcp_memcontrol: Kill struct tcp_memcontrol) falsly modified the access to memory_pressure of sk->sk_prot->memory_pressure. The patch did modify the memory_pressure-field of struct cg_proto, but not the one of struct proto. So, the access to sk_prot->memory_pressure should not be changed.
