REPOST patch 05/38: CLIENT: change inode to dentry in ->readdir()

This patch changes the interface of the ->readdir() nfs_rpc_op
so that its first argument is a dentry instead of an inode.

[Explanation: The dentry is required because in NFSv4, we need
to make use of the _parent_ directory's inode. This is because
NFSv4 servers no longer return an entry for ".." in the READDIR
response, so the client kernel needs to fake this entry, inode
number and all.]
