On a resume, when the power is lost during hibernate, the USB core will
call hub_reset_resume for the xHCI USB 2.0 roothub, but not for the USB
3.0 roothub:

[  164.748310] usb usb1: root hub lost power or was reset
[  164.748353] usb usb2: root hub lost power or was reset
[  164.748487] usb usb3: root hub lost power or was reset
[  164.748488] xhci_hcd 0000:01:00.0: Stop HCD
...
[  164.870039] hub 4-0:1.0: hub_resume
...
[  164.870054] hub 3-0:1.0: hub_reset_resume

This causes issues later, because the USB core assumes the USB 3.0 hub
attached to the USB 3.0 roothub is still active.  It attempts to queue a
control URB for the external hub, which fails because all the device
slot contexts were released when the USB 3.0 roothub lost power:

This causes issues when a USB 3.0 hard drive is attached to the external
USB 3.0 hub when the system is hibernated:

[ 6249.849653] sd 8:0:0:0: [sdb] Unhandled error code
[ 6249.849659] sd 8:0:0:0: [sdb]  Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK

[ 6249.849671] end_request: I/O error, dev sdb, sector 10760

Make sure to inform the USB core that *both* xHCI roothubs lost power.
