ENGR00125616 GPU: make sure device is stopped before close
When terminating some applications such as OpenGL ES2.0 conf. test,
kgsl_device_stop is not triggered. And run such kind of application
for several times, system hang happens for inconsistency of device
states. So make sure device is stopped in kgsl_device_close, which
is only called by last running caller process.
