net: phy-c45: Fix genphy_c45_ethtool_set_eee description

Browse Source 
The text has been cut/paste from genphy_c45_ethtool_get_eee but not
changed to reflect it performs set.

Additionally, extend the comment. This function implements the logic
that eee_enabled has global control over EEE. When eee_enabled is
false, no link modes will be advertised, and as a result, the MAC
should not transmit LPI.
