USB: OHCI: fix bug in controller resume

This patch (as1063) fixes a bug in the way ohci-hcd resumes its
controllers.  It leaves the Master Interrupt Enable bit turned off.

If the root hub is resumed immediately this won't matter.  But if the
root hub is suspended (say because no devices are plugged in), it won't
ever wake up by itself.
