xhci: Fix error path return value.
This patch fixes an issue discovered by Dan Carpenter:
The patch 3b3db026414b: "xhci: Add infrastructure for host-specific
LPM policies." from May 9, 2012, leads to the following warning:
drivers/usb/host/xhci.c:3909 xhci_get_timeout_no_hub_lpm()
warn: signedness bug returning '-22'
3906 default:
3907 dev_warn(&udev->dev, "%s: Can't get timeout for non-U1 or U2 state.\n",
3908 __func__);
3909 return -EINVAL;
^^^^^^^^^^^^^^
This should be a u16 like USB3_LPM_DISABLED or something.
3910 }

3912 if (sel <= max_sel_pel && pel <= max_sel_pel)
3913 return USB3_LPM_DEVICE_INITIATED;
