amdgpu_userq_hang_detect_work() retrieves the queue pointer using
container_of() from the embedded work item.
Since the work structure is part of struct amdgpu_usermode_queue,
the returned queue pointer cannot be NULL in normal execution.
Remove the redundant !queue check and keep the validation for
queue->userq_mgr.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/amdgpu_userq.c:159 amdgpu_userq_hang_detect_work()
warn: can 'queue' even be NULL?
Fixes: 290f46cf5726 ("drm/amdgpu: Implement user queue reset functionality")
