ethtool: untangle the linkmode and ethtool headers
Commit 26c5334d344d ("ethtool: Add forced speed to supported link modes maps") added a dependency between ethtool.h and linkmode.h. The dependency in the opposite direction already exists so the new code was inserted in an awkward place. The reason for ethtool.h to include linkmode.h, is that ethtool_forced_speed_maps_init() is a static inline helper. That's not really necessary.
