[PATCH] ethtool: fix long statistics name

[Stephen Hemminger <shemminger@osdl.org>]

Fix handling of statistics where the label is exactly 32 (ETH_GSTRING_LEN)
characters long (observed with chelsio 10G driver). 
Before it would print garbage because of going by end
of string. Don't need to copy string, just use formats properly.
