usb: gadget: udc: renesas_usb3: fix error return code in renesas_usb3_probe()

Browse source

platform_get_irq() returns an error code, but the renesas_usb3 driver
ignores it and always returns -ENODEV. This is not correct and,
prevents -EPROBE_DEFER from being propagated properly.

Also, notice that platform_get_irq() no longer returns 0 on error:

Print error message and propagate the return value of platform_get_irq
on failure.

This issue was detected with the help of Coccinelle.
