gpu: nvgpu: skip suspend if gpu already removed
On nvgpu module unload, platform_driver_unregister() detaches
driver from device (driver_detach()). As part of this,
__device_release_driver() results a race between driver's
.runtime_resume(), .remove() and .runtime_suspend().
As nvgpu's .remove() is handling all steps of cleaning up
driver state and shutting down gpu, .runtime_suspend()
shall have no work. So skip .runtime_suspend() is gk20a *g
has already been processed.
