igb: Change IGB_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 igb devices can use as low as 64 descriptors.
This change will unify igb with other drivers.
Based on commit 7b1be1987c1e ("e1000e: lower ring minimum size to 64")
Fixes: 9d5c824399de ("igb: PCI-Express 82575 Gigabit Ethernet driver")
