[XFRM] netlink: Inline attach_encap_tmpl(), attach_sec_ctx(), and attach_one_addr()
These functions are only used once and are a lot easier to understand if inlined directly into the function. Fixes by Masahide NAKAMURA. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
