[ Upstream commit 66cce9e73ec61967ed1f97f30cee79bd9a2bb7ee ] When a remote usb device is attached to the local Virtual USB Host Controller Root Hub port, the bound device driver may send a port reset command. vhci_hcd accepts port resets only when the device doesn't have port address assigned to it. When reset happens device is in assigned/used state and vhci_hcd rejects it leaving the port in a stuck state. This problem was found when a blue-tooth or xbox wireless dongle was passed through using usbip. A few drivers reset the port during probe including mt76 driver specific to this bug report. Fix the problem with a change to honor reset requests when device is in used state (VDEV_ST_USED).
