[ 15/66] drm/radeon: Calling object_unrefer() when creating fb failure

[Ben Hutchings]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: liu chuansheng <chuansheng.liu@xxxxxxxxx>

commit f2d68cf4daa4de97d400d94836b907e35228e54f upstream.

When kzalloc() failed in radeon_user_framebuffer_create(), need to
call object_unreference() to match the object_reference().
