Jeff Layton 1b3c6d07e2 pnfs: make pnfs_layout_process more robust 
It can return NULL if layoutgets are blocked currently. Fix it to return
-EAGAIN in that case, so we can properly handle it in pnfs_update_layout.

Also, clean up and simplify the error handling -- eliminate "status" and
just use "lseg".
