Subject: [PATCH 1/2] usbip: Remove repeated setting of hcd->state in vhci_bus_suspend()

When hcd suspends execution, hcd_bus_suspend() calls vhci_bus_suspend()
which sets hcd->state as HC_STATE_SUSPENDED. But after calling
vhci_bus_suspend(), hcd_bus_suspend() also sets hcd->state as
HC_STATE_SUSPENDED.
So, setting hcd->state in vhci_hcd_suspend() is unnecessary.
