Subject: NFS: Enabling v4.2 should not recompile nfsd and lockd

commit 694e096fd7c2a7d40760fc9c9dfc826bdd495ea4 upstream.

When CONFIG_NFS_V4_2 is toggled nfsd and lockd will be recompiled,
instead of only the nfs client.  This patch moves a small amount of code
into the client directory to avoid unnecessary recompiles.
