From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>
commit 3a8839bbb86da7968a792123ed2296d063871a52 upstream.
Device attribute group @usb3_hardware_lpm_attr_group is merged by
add_power_attributes(), but it is not unmerged explicitly, fixed by
unmerging it in remove_power_attributes().
Fixes: 655fe4effe0f ("usbcore: add sysfs support to xHCI usb3 hardware LPM")
