gpu: nvgpu: remove dead code for get gr runlist_id

Browse Source 
nvgpu_engine_get_gr_runlist_id gets the first instance of
active GR engine using nvgpu_engine_get_ids. Therefore the
engine_id is already known to be valid.
Remove call to nvgpu_engine_get_active_eng_info (which iterates
all engines), and fetch f->engine_info[engine_id] instead.
Also remove non-NULL test for engine_info, which could not
be true.

Jira NVGPU-4511
