[NET]: Make netlink_kernel_release publically available as sk_release_kernel.
This staff will be needed for non-netlink kernel sockets, which should also not pin a namespace like tcp_socket and icmp_socket. Signed-off-by: Denis V. Lunev <den@openvz.org> Acked-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
