Subject: usb: host: xhci-plat: propagate return value of platform_get_irq()

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

commit 4b148d5144d64ee135b8924350cb0b3a7fd21150 upstream.

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