drm - Fix major stalls by fixing an improper taskqueue priority

* drm was creating task queues with a LWKT priority of 0, which is
  lower than the priority of a running user thread.

* Fix all cases where improper priorities are passed to
  taskqueue_start_threads().  This fixes major video stalls and glitches
  that occur when other things might be running on the system cpu-bound.

* taskqueue_start_threads() now asserts if the priority passed to it is
  illegal.
