Benjamin Coddington 85aa8ddc38 NFS: Trigger the "ls -l" readdir heuristic sooner 
Since commit 1a34c8c9a49e ("NFS: Support larger readdir buffers") has
updated dtsize, and with recent improvements to the READDIRPLUS helper
heuristic, the heuristic may not trigger until many dentries are emitted
to userspace.   This will cause many thousands of GETATTR calls for "ls
-l" when the directory's pagecache has already been populated.  This
manifests as poor performance for long directory listings after an
initially fast "ls -l".

Fix this by emitting only 17 entries for any first pass through the NFS
directory's ->iterate_shared(), which allows userpace to prime the
counters for the heuristic.
