gpu: nvgpu: mark thread stopped when it independently quits
It's technically possible for a thread to exit without first calling
nvgpu_thread_stop() in another, so mark the thread exit status from the
thread after it has finished instead of in nvgpu_thread_stop(). Do this
by starting the thread as a proxy function which calls the actual thread
function and then sets the flag.
Also, add a new flag to actually signify the running state because the
thread->task going null abruptly would break nvgpu_thread_stop().
This does not guarantee that the kernel thread itself has stopped, but
the function which can be considered as an "nvgpu thread" will be.
