usbip: list: don't list devices attached to vhci_hcd

Browse source 
commit ef824501f50846589f02173d73ce3fe6021a9d2a upstream.

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.
