USB: UHCI: remove uses of hcd->state
This patch (as1456) removes all uses of hcd->state from the uhci-hcd
driver, as part of the overall strategy to eliminate hcd->state
completely. Now when a controller dies we call usb_hc_died()
directly, instead of relying on the core interrupt handler to see that
hcd->state has changed to HC_STATE_HALT and make the call for us.
