pnfs: update layout state on layoutget/return/recall

Browse source 
on a successful LAYOUTGET, file_layout_fetch() calls layout_update() to copy the first layout segment returned and update the layout stateid
on a successful LAYOUTRETURN, file_layout_return() frees the layout segment and updates/clears the stateid
