[PATCH 1/3] netfilter: Fix copy_to_user too small size parametre.

From: Santosh Nayak <santoshprasadnayak <at> gmail.com>

While copying to userspace, the size of source is 29byte where as
size parametre is 32 byte.  Its leaking extra-information from
kernel space to user space.
Replace EBT_FUNCTION_MAXNAMELEN by XT_EXTENSION_MAXNAMELEN.
