Warner Losh 58a745889f Rather than havnig enabled/disabled, implement a max queue depth. ...

While usually not an issue, this firewalls bugs in the code that may
run us out of memory.

Fix a memory exhaustion in the case where devctl was disabled, but the
link was bouncing.  The check to queue was in the wrong place.

Implement a new sysctl hw.bus.devctl_queue to control the depth.  Make
compatibility hacks for hw.bus.devctl_disable to ease transition.
