usbhub: rewrite port handling

The state space of a usb hub port is a bit more complex than what was
there originally. Got rid of the active operations counting, and
replaced that with finite state machine. Fixes a lot of race conditions
and lack of synchronization when connect and disconnect events come very
fast.
