Jonas Blixt 2b391eb17a USB: usbip: fix stub_dev hub disconnect
[ Upstream commit 97475763484245916735a1aa9a3310a01d46b008 ]

If a hub is disconnected that has device(s) that's attached to the usbip layer
the disconnect function might fail because it tries to release the port
on an already disconnected hub.
