igc: Fix typo in i225 LTR functions
The LTR maximum value was incorrectly written using the scale from the LTR minimum value. This would cause incorrect values to be sent, in cases where the initial calculation lead to different min/max scales. Fixes: 707abf069548 ("igc: Add initial LTR support") Suggested-by: Dima Ruinskiy <dima.ruinskiy@intel.com> Signed-off-by: Sasha Neftin <sasha.neftin@intel.com> Tested-by: Nechama Kraus <nechamax.kraus@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
