3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Weston Andros Adamson <dros@xxxxxxxxxxxxxxx>
commit abad2fa5ba67725a3f9c376c8cfe76fbe94a3041 upstream.
If clp is new (cl_count = 1) and it matches another client in
nfs4_discover_server_trunking, the nfs_put_client will free clp before
->cl_preserve_clid is set.
