blkg is scheduled to be unified for all policies and thus there won't be one-to-one mapping from blkg to policy. Update stat related functions to take explicit @pol or @plid arguments and not use blkg->plid. This is painful for now but most of specific stat interface functions will be replaced with a handful of generic helpers.
