net: ethtool: correct MAX attribute value for stats

Browse Source 
[ Upstream commit 52f79609c0 ]

When compiling YNL generated code compiler complains about
array-initializer-out-of-bounds. Turns out the MAX value
for STATS_GRP uses the value for STATS.

This may lead to random corruptions in user space (kernel
itself doesn't use this value as it never parses stats).

Fixes: f09ea6fb12 ("ethtool: add a new command for reading standard stats")
