have an active session. We have no other interrupts after disconnect
coming in this case at least with the omap2430 glue.
Let's fix the issue by checking the interrupt status again with
delayed work for the devctl 99 case. In the suspend after disconnect
case the devctl session bit has cleared by then and musb can idle.
For a typical USB B-device connect case we just continue with normal
interrupts.
