NFSv4: Retrieve attributes _before_ calling delegreturn
In order to retrieve cache consistency attributes before
anyone else has a chance to change the inode, we need to
put the GETATTR op _before_ the DELEGRETURN op.
We can then use that as part of a 'nfs_post_op_update_inode_force_wcc()'
call, to ensure that we update the attributes without clearing our
cached data.
