net: bcmgenet: Check for Wake-on-LAN interrupt probe deferral
The interrupt controller supplying the Wake-on-LAN interrupt line maybe
modular on some platforms (irq-bcm7038-l1.c) and might be probed at a
later time than the GENET driver. We need to specifically check for
-EPROBE_DEFER and propagate that error to ensure that we eventually
fetch the interrupt descriptor.
Fixes: 9deb48b53e7f ("bcmgenet: add WOL IRQ check")
Fixes: 5b1f0e62941b ("net: bcmgenet: Avoid touching non-existent interrupt")
