ice: remove invalid parameter of equalizer

It occurred that in the commit 70838938e89c ("ice: Implement driver
functionality to dump serdes equalizer values") the invalid DRATE parameter
for reading has been added. The output of the command:

  $ ethtool -d <ethX>

returns the garbage value in the place where DRATE value should be
stored.

Remove mentioned parameter to prevent return of corrupted data to
userspace.
