igc: Fix hicredit calculation
According to the Intel Software Manual for I225, Section 7.5.2.7,
hicredit should be multiplied by the constant link-rate value, 0x7736.
Currently, the old constant link-rate value, 0x7735, from the boards
supported on igb are being used, most likely due to a copy'n'paste, as
the rest of the logic is the same for both drivers.
Update hicredit accordingly.
Fixes: 1ab011b0bf07 ("igc: Add support for CBS offloading")
