igc: Change IGC_MIN to allow set rx/tx value between 64 and 80
Change the minimum value of RX/TX descriptors to 64 to enable setting the rx/tx
value between 64 and 80. All igc devices can use as low as 64 descriptors.
This change will unify igc with other drivers.
Based on commit 7b1be1987c1e ("e1000e: lower ring minimum size to 64")
Fixes: 0507ef8a0372 ("igc: Add transmit and receive fastpath and interrupt handlers")
