ethtool: Fix link extended state for big endian
[ Upstream commit e2f08207 ] The link extended sub-states are assigned as enum that is an integer size but read from a union as u8, this is working for small values on little endian systems but for big endian this always give 0. Fix the variable in the union to match the enum size.
