[Sheepdog] [PATCH] farm: refine the read_working_object() output

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

When the object is not found in working direcotry, it not an error
case, we should retrofit the debug message to be more friendly

  read_working_object(362) failed to open /home/tailai.ly/shee \
  pdog/store/0/obj/00fd34af00000015: No such file or directory

		       |
		       V
  read_working_object(362) object fd34af00000015 not found
