Jordan Crouse 0041ba396d drm/msm: Don't allow zero sized buffer objects ...

Zero sized buffer objects tend to make various bits of the GEM
infrastructure complain:

 WARNING: CPU: 1 PID: 2323 at drivers/gpu/drm/drm_mm.c:389 drm_mm_insert_node_generic+0x258/0x2f0

 PC is at drm_mm_insert_node_generic+0x258/0x2f0
 LR is at drm_vma_offset_add+0x4c/0x70

Zero sized buffers serve no appreciable value to the user so disallow
them at create time.
