gpu: nvgpu: Use struct to hold gk20a pointer
The private_data field in the file pointer passed to release() for
channels originally pointed directly to the referenced channel. The
problem with this is that when the driver is killed and the channel
mmeory is freed that pointer becomes invalid.
The necessity of that channel is to get access to the gk20a struct that
owns the channel. This can instead be accomplished by making a new
private data struct that has a pointer to the gk20a struct directly
instead of requiring the channel to be valid. This lets the release()
function work even if the channels are gone (though in such cases the
release function doesn't do very much).
