Change Details

Rather than using taskqueue_swi_giant which holds Giant for all deferred destroy_dev calls, instead lock Giant explicitly around the caller-supplied callback passed to destroy_dev_sched_cb only when D_NEEDGIANT is set. In addition, switch to taskqueue_thread for destroy_dev_sched. Deferred destroy_dev requests don't need to run at an SWI priority.

In addition, switch to taskqueue_thread for destroy_dev_sched. Deferred destroy_dev requests don't need to run at an SWI priority.
