USB: OHCI: turn off RD when remote wakeup is disabled

This patch (as1068b) disables the RD interrupt flag when an OHCI root
hub is suspended with remote wakeup disabled.  Although the spec
clearly states that this flag permits the controller to issue an
interrupt when a resume request from downstream is detected and not
when a local status change occurs, some controllers mistakenly use it
for both types of event.
