gpu: nvgpu: use instance specific runlist id

Browse Source 
In __gk20a_channel_open(), if runlist_id is provided as -1,
pick up correct GPU instance sprcific default runlist id using
nvgpu_grmgr_get_gpu_instance_runlist_id().
Also, get GPU instance is using nvgpu_get_gpu_instance_id_from_cdev()

If runlist_id is received as input, check if it is valid for given
GPU instance with nvgpu_grmgr_is_valid_runlist_id()
