Currently the removal from bdi->wb_list happens directly in
cgwb_release_workfn(). Move it to wb_shutdown() which is functionally
equivalent and more logical (the list gets only used for distributing
writeback works among bdi_writeback structures). It will also allow us
to simplify writeback shutdown in cgwb_bdi_destroy().
