ethernet: 8390: Remove unnecessary print function dev_err()

The print function dev_err() is redundant because platform_get_irq()
already prints an error.

Eliminate the follow coccicheck warning:
./drivers/net/ethernet/8390/mcf8390.c:414:2-9: line 414 is redundant
because platform_get_irq() already prints an error
