net: ethernet: xilinx: Do not use NO_IRQ in axienet
This driver is used on Microblaze and will be used on Arm Zynq. Microblaze doesn't define NO_IRQ and no IRQ is 0. Arm still uses NO_IRQ as -1 and there is no option to connect IRQ to irq 0. That's why <= 0 is only one option how to find out undefined IRQ. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
