[ 03/16] drm/radeon: Calling object_unrefer() when creating fb failure

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

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

From: liu chuansheng <chuansheng.liu@intel.com>

commit f2d68cf4daa4de97d400d94836b907e35228e54f upstream.

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