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 Modules linked in: CPU: 1 PID: 2323 Comm: drm-api-test Tainted: G W 4.9.0-rc4-00906-g693af44 #213 Hardware name: Qualcomm Technologies, Inc. DB820c (DT) task: ffff8000d7353400 task.stack: ffff8000d7720000 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.
