net: dsa: microchip: ptp: Fix checks on irq_find_mapping()
irq_find_mapping() returns a positive IRQ number or 0 if no IRQ is found
but it never returns a negative value. However, during the PTP IRQ setup,
we verify that its returned value isn't negative.
Fix the irq_find_mapping() check to enter the error path when 0 is
returned. Return -EINVAL in such case.
