sungem: update gp->reset_task flushing
gp->reset_task_pending is always set right before reset_task is
scheduled and as there is no synchronization between the setting and
scheduling, busy looping on reset_task_pending before flushing
reset_task doesn't really buy anything.
Directly flush gp->reset_task on suspend and cancel on detach.
