Note that when a new netns is created, it inherits its
sysctl_tcp_rmem and sysctl_tcp_wmem from initial netns.
This change is needed so that we can refine TCP rcvbuf autotuning,

[alakeshh: backport to v4.14: The patch does not apply to v4.14

the function tcp_select_initial_window had to be changed to be able
to pass pointer to struct sock.]
