net: marvell: mvmdio: Handle errors from optional IRQ lookup

Browse source

platform_get_irq_optional() returns a positive IRQ number on success or
a negative error code on failure. For an optional IRQ, -ENXIO indicates
that no optional IRQ is available. Other errors should be propagated so
that the caller can handle them appropriately.

The existing code propagates -EPROBE_DEFER, but ignores other negative
errors. Propagate negative errors other than -ENXIO.

Found by manual code inspection.
