This fixes two small and unrelated bugs in the current OHCI code:

  - Certain initialization sequences had problems with IRQs.
    Fixed last month in EHCI, but this ohci patch didn't seem
    needed back then.  OK, so now I saw the same bug in OHCI.
    (I could believe UHCI needs it too, sigh.)

  - When restarting endpoint i/o after a queue fault, the HC
    needs to be told the control (or bulk) list filled (CLF/BLF).
    Likely this wasn't common (usbtest test10 subcase7 fault
    recovery reproduced it nicely).

Please merge.  Lack of the first one might make trouble for
some people.
