Revert "net: mvmdio: avoid error message for optional IRQ"

Browse Source 
This reverts commit e1f550dc44.
platform_get_irq_optional() will still return -ENXIO when no interrupt
is provided so the additional error handling caused the driver prone to
fail when no interrupt was specified. Revert the change so we can apply
the correct minimal fix.
