net: fec: Handle optional IRQ lookup errors correctly

Browse source

Handle errors from platform_get_irq_byname_optional() explicitly while
preserving the existing fallback to platform_get_irq() when the named IRQ
is not available.

Propagate errors other than -ENXIO from the optional IRQ lookup instead
of silently falling back to the indexed IRQ lookup.

In particular, silently ignoring -EPROBE_DEFER can cause the driver to
continue probing instead of deferring as required.
