USB: core: Disable LPM only for non-suspended ports
There's USB error when tegra board is shutting down:
[ 180.919315] usb 2-3: Failed to set U1 timeout to 0x0,error code -113
[ 180.919995] usb 2-3: Failed to set U1 timeout to 0xa,error code -113
[ 180.920512] usb 2-3: Failed to set U2 timeout to 0x4,error code -113
[ 186.157172] tegra-xusb 3610000.usb: xHCI host controller not responding, assume dead
[ 186.157858] tegra-xusb 3610000.usb: HC died; cleaning up
[ 186.317280] tegra-xusb 3610000.usb: Timeout while waiting for evaluate context command
The issue is caused by disabling LPM on already suspended ports.
For USB2 LPM, the LPM is already disabled during port suspend. For USB3
LPM, port won't transit to U1/U2 when it's already suspended in U3,
hence disabling LPM is only needed for ports that are not suspended.
