xhci used to test if link power management (LPM) capable USB2 devices
really could enter and exit L1 state link state.
Failed devices were added to a lpm_failed_dev list.
This feature was removed 9 years ago in
commit de68bab4fa96 ("usb: Don't enable USB 2.0 Link PM by default.")
but lpm_failed_dev member was still left.
Remove it now.
