ethtool: adjust struct ethtool_keee to kernel needs

This patch changes the following in struct ethtool_keee
- remove member cmd, it's not needed on kernel side
- remove reserved fields
- switch the semantically boolean members to type bool

We don't have to change any user of the boolean members due to the
implicit casting from/to bool. A small change is needed where a
pointer to bool members is used, in addition remove few now unneeded
double negations.
