net: Move "struct net" declaration inside the __KERNEL__ macro guard
This patch reduces namespace pollution by moving the "struct net" declaration
out of the userspace-facing portion of linux/netlink.h. It has no impact on
the kernel.
(This came up because we have several C++ applications which use "net" as a
namespace name.)
