===============
[ Upstream commit ef824501f50846589f02173d73ce3fe6021a9d2a ]
usbip host lists devices attached to vhci_hcd on the same server when user does attach over localhost or specifies the server as the remote.
usbip attach -r localhost -b busid or usbip attach -r servername (or server IP)
Fix it to check and not list devices that are attached to vhci_hcd.
