  MFC: r324074
  Fix a memory leak that occurred in the pNFS client.
  
  When a "pnfs" NFSv4.1 mount was unmounted, it didn't free up the layouts
  and deviceinfo structures. This leak only affects "pnfs" mounts and only
  when the mount is umounted.
  Found while testing the pNFS Flexible File layout client code.
