#1328374 — [PATCH v2] net: smc91x: propagate irq return code

The smc91x driver doesn't honor the probe deferral mechanism when the
interrupt source is not yet available, such as one provided by a gpio
controller not probed.

Fix this by propagating the platform_get_irq() error code as the probe
return value.
