xhci: Do not issue device reset when device is not setup
xHCI controllers respond to a Reset Device command when the Slot is in the
Enabled/Disabled state by returning an error. This is fine on other host
controllers, but the Etron xHCI host controller returns a vendor-specific
error code that the xHCI driver doesn't understand. The xHCI driver then
gives up on device enumeration.
Instead of issuing a command that will fail, just return. This fixes the
issue with the xhci driver not working on ASRock P67 Pro/Extreme boards.
This should be backported to stable kernels as far back as 2.6.34.
