hash_xlog.h included descriptions for the blocks used in WAL records
that were was not completely consistent with how the records are
generated, with one block missing for SQUEEZE_PAGE, and inconsistent

This information was incorrect since c11453ce0a, cross-checking the
logic for the record generation.
