Fix a memory leak that occurred in the pNFS client.

Browse Source 
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.
