3.10-stable review patch. If anyone has any objections, please let me know.

From: Mathias Krause <mini...@googlemail.com>
[ Upstream commit 6865d1e834be84ddd5808d93d5035b492346c64a ]
When filling the netlink message we miss to wipe the pad field,
therefore leak one byte of heap memory to userland. Fix this by
setting pad to 0.
