msm: kgsl: flush device workqueue before stop

Make sure the irq is off, the idle timer is
stopped and the workqueue is flushed before
stopping the device for early suspend, suspend,
last release or hang recovery. There is one case
where the workqueue cannot be flushed, which is from
kgsl_pwrctrl_sleep() when going into SLUMBER
state. This codepath can be called from the
workqueue itself so flushing would deadlock.
