connector: use nlmsg_len() to check message length
[ Upstream commit 162b2bedc084d2d908a04c93383ba02348b648b0 ]
The current code tests the length of the whole netlink message to be
at least as long to fit a cn_msg. This is wrong as nlmsg_len includes
the length of the netlink message header. Use nlmsg_len() instead to
fix this "off-by-NLMSG_HDRLEN" size check.
