usb: host: ohci-pxa27x: propagate the irq error code
In several drivers in the pxa architecture, it was found that the platform_get_irq() was not propagated. This breaks the the device-tree probe deferral path, if -EPROBE_DEFER is returned. Unfortunately, the error return in this case is transformed into -ENXIO, breaking the deferral mechanism. Even if in this specific case the driver was not broken, because the interrupt controller is always probed before drivers, propagate the proper return code.
