inet: preserve const qualifier in inet_sk()
We can change inet_sk() to propagate const qualifier of its argument.
This should avoid some potential errors caused by accidental
(const -> not_const) promotion.
Other helpers like tcp_sk(), udp_sk(), raw_sk() will be handled
in separate patch series.
v2: use container_of_const() as advised by Jakub and Linus
