net: dsa: microchip: common: 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, on each
irq_find_mapping() call, we verify that the returned value isn't
negative.
Fix the irq_find_mapping() checks to enter error paths when 0 is
returned. Return -EINVAL in such cases.
