channel_joblist_peek() returns NULL if the list is empty. nvgpu_channel_joblist_is_empty() has been used only together with that function; remove it and check against NULL to see whether there are jobs in flight. This removes some duplication, simplifies the call sites slightly, and gets rid of a Coverity nag about a possible NULL pointer from peek that really isn't (when the emptiness was already checked).
