[NETNS][IPV6] Move sysctl initialization later on in the IPv6 init sequence

This patch moves initialization of IPv6 sysctl stuff at the end of
IPv6 initialization.

This will be helpful for network namespaces where some sysctl entries
depend on per-namespace variables, that need to be allocated and
initialized before they are referenced by sysctl.

[TCP]: TCP cubic v2.2

We have updated CUBIC to fix some issues with slow increase in large
BDP networks. We also improved its convergence speed. The fix is in
fact very simple -- the window increase limit of smax during the
window probing phase (i.e., convex growth phase) is removed. We found
that this does not affect TCP friendliness, but only improves its
