[PATCH] drm/amdgpu: Allow to create BO lists in CS ioctl.

[Andrey Grodzovsky]

This was to avoid extra code in amdgpu_cs_parser_bos when 
amdgpu_bo_list_get is called. But I see your argument about random id 
guess (practically unrealistic to happen but still a valid argument). I 
will do some minor alterations to avoid this and respin the patch.
