docs/admin-guide/mm: remove useless markup

It is enough to use a file name to cross-reference another rst document.

Jon says:
  The right things will happen in the HTML output, readers of the
  plain-text will know immediately where to go, and we don't have to add
  the label clutter.

Drop reference markup and unnecessary labels and use plain file names.

 Another, more recent, mechanism that enables use of the huge pages is
 called `Transparent HugePages`, or THP. Unlike the hugetlbfs that
 requires users and/or system administrators to configure what parts of
 the system memory should and can be mapped by the huge pages, THP
 manages such mappings transparently to the user and hence the
