rtnl: stats - add missing netlink message size checks
[ Upstream commit 4775cc1f2d5abca894ac32774eefc22c45347d1c ]
We miss to check if the netlink message is actually big enough to contain
a struct if_stats_msg.
Add a check to prevent userland from sending us short messages that would
make us access memory beyond the end of the message.
