Thomas Fleury 45b99f67b2 gpu: nvgpu: remove dead code for runlist_id check ...

nvgpu_engine_is_valid_runlist_id already iterates the list of
active engines, 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.

Also make sure to reset num_engines in nvgpu_cleanup_sw, to avoid
accessing uninitialized active_engines_list in unit test corner
cases (targetting init/remove support).
