netlink: make sure we reserve space for NLMSG_DONE
Otherwise, if messages pack really close together, we'll exceed the size
of the sk_buff and return ENOBUFS. I suspect this has been the cause of
a lot of weird bugs that people just worked around by increasing the
receive buffer size. This actually addresses the root cause.
