osdc/Objecter: force pg_read ops to ignore cache overlay

pg_read is only used for PG listing and hit_set_{list,get}; these
operations can't and shouldn't consider the tiering overlay.

This makes the _calc_target behavior with the explicit pgid make sense;
otherwise, what would it mean to try to read pg x.1 from pool x and get
redirected to pg y.1 in pool y?
