[COMMON] g2d: schedule the task directly on ioctl

Task of g2d should be scheduled on process context
due to power management, so every task are executed
on workqueue. However, task on state that all
fences are signaled on ioctl could be scheduled
directly without queueing and it make remove the delay
for workqueue.
