ENGR00270996 net:fec: fix fec probe fail due to gpio_irq check error

Board files correctly define fec gpio irq to wake up wait mode since FEC
interrupt cannot connect to GPC, otherwise board files define fec gpio irq
to -1. So, fec probe function check the gpio irq to decide whether fec use
gpio irq or fec irq.

Current irq checking logic is incorrect. Correct the gpio irq checking.
