[sheepdog] [PATCH stable-0.8 1/2] sheep/md: add main_fn marker to for_each_object_in_wd()

[Hitoshi Mitake]

From: Robin Dong <sanbai at taobao.com>

We should add the main_fn marker to for_each_object_in_wd() because
the function for_each_object_in_wd() could only be called in main
threads at present.
