  1. src: simplify large pages mapping code 

    * Introduce `OnScopeLeave` handler for cleaning up mmap()ed range(s).
* Factor out failure scenario at the bottom of the function with
  `fail` label for use with `goto`.
* Do not allocate temporary range (`nmem`) on FreeBSD, because it is
  not used.

The intention is that the steps involved in re-mapping to large pages
become more clearly visible.
