[PATCH] knfsd: mark NFS/TCP server not EXPERIMENTAL

From: Greg Banks <gnb@sgi.com>

NFS/TCP has been used widely for a long time now, and is now enabled by many
distros and typically recommended for lossy or congested networks.  This patch
removes the EXPERIMENTAL tag, updates the help text, and changes arch
defconfigs to set it by default (note that several already did so).
