Also forgotten in the previous that removed the permanent double mapping

of low physical memory:

Update the comment about leaving the permanent mapping in place.  This
also improves the wording of the comment.  PTD 0 is still left alone
because it is fairly important that it was unmapped earlier, and the
comment now describes the unmapping of the other low PTDs that the code
actually does.
