Revert ListPostings change (#12955) 
Reverts change from https://github.com/prometheus/prometheus/pull/12906

The benchmarks show that it's slower when intersecting, which is a
common usage for ListPostings (when intersecting matchers from Head)

(old is before #12906, new is #12906):

                           │     old     │                 new                 │
                           │   sec/op    │   sec/op     vs base                │
Intersect/LongPostings1-16   20.54µ ± 1%   21.11µ ± 1%   +2.76% (p=0.000 n=20)
Intersect/LongPostings2-16   51.03m ± 1%   52.40m ± 2%   +2.69% (p=0.000 n=20)
Intersect/ManyPostings-16    194.2m ± 3%   332.1m ± 1%  +71.00% (p=0.000 n=20)
geomean                      5.882m        7.161m       +21.74%
