[PATCH v1 07/24] net/igc/base: fix typo in LTR calculation

[Anatoly Burakov]

From: Dima Ruinskiy <dima.ruinskiy at intel.com>

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. Fix the
typo to correctly calculate the LTR maximum value.

Fixes: 8cb7c57d9b3c ("net/igc: support device initialization")
